  Several Non-invasive Profile Monitors are being in-stalled along the accelerator to support the commissioning, tuning and operation of the powerful proton based ESS linear accelerator. In the low energy parts of the ESS linac (3.6 MeV to 90 MeV), the residual gas pressure is high enough to measure the transverse beam profile by using fluorescence induced by the beam on the gas molecules. However, in the ESS linac sections above 90 MeV, protons are accelerated by superconductive cavities working at cryogenic temperatures and high vacuum. Therefore, the signal based on the fluorescence process is too weak, while ionization can counteract this drawback. We have provided five IPM (Ionization Profile Monitors) pairs for energies ranging from 100 to 600 MeV. The design of such monitors is challenging due to weak signal (as a result of high proton energy and low pressure <10-9 mbar), tight space constraints inside the vacuum chamber, space charge effect, ISO-5 cleanliness requirement, and electrode polarization at ±15 kV. This publication will detail the development we followed to fulfil the ESS requirements.

  In the scope of SOLEIL II, the booster must also be upgraded to reduce from 130 to 5~nm.rad the emittance of the beam delivered to the ring. Control of the emittance in the booster will become crucial to ensure the nominal performance of the storage ring injection. The SOLEIL I booster is already equipped with a Visible Synchrotron Radiation Monitor (MRSV). This equipment, made of an extraction mirror and a simple optical system, was originally planned to be used only for beam presence verification but has not been used routinely for operation since the commissioning in 2005. The control and acquisition systems had to be refreshed to be usable again and allow the beam size measurement along the booster energy ramp. The extraction mirror was replaced due to unexpected degradation leading to a second spot appearing on the camera. This paper traces back the MRSV upgrades from understanding the cause of mirror degradation until mirror replacement and the first proper beam visualisation, achieved at the beginning of 2023.

WEP005 Effect of Incoherent Depth of Field for Bean Halo Measurement with the Coronagraph in SuperKEKB 335
 
  • T.M. Mitsuhashi, H. Ikeda, G. Mitsukapresenter
    KEK, Ibaraki, Japan
  
  The incoherent depth-of-field due to the instantaneous opening angle of dipole SR will reduce the spatial coherence of SR in horizontal direction in the beam size measurement by using interferometry. This reduction of spatial coherence is due to both of apparent change of the beam profile due to field depth and intensity distribution in the aperture. In the case of beam profile measurement by imaging system, observed beam profile will deform and produce a beam tail in asymmetric manner by this effect. This apparent change of beam profile, especially extra beam tail in one side has certain influence for beam halo measurement using the coronagraph, because it has a large dynamic range of 6 order magnitude. Since the magnitude of asymmetric tail is proportional to bending radius, this effect is larger in large high energy physics machine which has a long bending radius. This effect is theoretically studied and compare with coronagraph measurement result of beam halo in the SuperKEKB. As a conclusion, this effect is very small and not observable in the coronagraph measurement at SuperKEKB.

  At the Center for Nuclear Study of the University of Tokyo, the measurement of Electric Dipole Moment of Francium (Fr) is underway with the world highest precision. Fr is generated by nuclear fusion reaction by irradiating gold with oxygen ion beam accelerated by RIKEN AVF Cyclotron. The required beam intensity is 18 eµA or more. However, the average beam transport efficiency drops to be around 66 % as the beam intensity exceeds 10 eµA. To solve the problem, a pepper-pot emittance monitor (PEM) for high-intensity beams has been developed. Referencing the PEM used for the injection beams of AVF Cyclotron, we have developed three additional items. The first is reducing the radiation damage to a camera, which is placed away from the beamline. The distance between the camera and PEM is 2.2 m, and the average image position accuracy of 0.15 mm is achieved. The second is the angular accuracy suitable for the accelerated beam. The required angular accuracy is estimated to be less than 0.3 mrad. A beam test for the first and second items is planned. The third is a beam shutter system to prevent PEM from heating due to beam. The measurement time by the system reaches 0.27 seconds now.

  The newly constructed superconducting linear accelerator (SRILAC) is now in operation with the aim of discovering new superheavy elements and advancing the production of medical radiation isotopes. Because it is crucial to extend the durability of the expensive Cm target for as long as possible, these experiments require the accelerated V beam to be sufficiently widened. To this end, a helium gas light emission monitor (HeLM) has been introduced to measure the beam profile. Because He gas flows within the target chamber, by capturing the light emitted from He gas with a CCD camera, the beam profile can be obtained nondestructively and continuously. These measurements are handled through programming in LabVIEW, with analyzed data integrated into an EPICS control system. A method to estimate the beam envelope has been recently developed by leveraging the measured quadrupole moments with beam energy position monitors (BEPMs), and incorporating calculations of the transfer matrix. The synergistic use of HeLM and BEPM plays a useful role in accurately controlling the beam size at the Cm target.

  The emittance reflectes the quality of the beam which is an important parameter of ion source. Oscillation of emittance and Twiss parameters in the negative ion (H−) beam is measured by application of a double-slit emittance monitor located at the RFQ entrance. The systematic error was valued in emittance measurement of CSNS RF ion source. This article mainly discussed the measurement accuracy and reliability of the double-slit emittance meter. Therefore it is shown that the working principle, mechanical disign, electronics and the application in CSNS RF ion source were introduced.

  The decrease of beam emittance in the 4th generation light source greatly increases the electron density, thus the wakefields and beam impedance in the storage ring are significantly enhanced, resulting in various beam instabilities. Therefore, it is necessary to observe the transient state of beams using the bunch-by-bunch technique, so as to dig into these instabilities. Here a three-dimensional (3D) positions measurement instrument is designed based on data synchronization module (DSM) to acquire the transverse positions and longitudinal phases of beams in real-time.

 A Compact IPM Capable of Measuring Two-Dimensional Profiles with the Constraint Magnet and Multi-channel Acquisition Electronics  
 
  • H.M. Xie
    IMP/CAS, Lanzhou, People’s Republic of China
  
  A compact IPM structure is proposed and developed for the HIAF project (High Intensity Heavy-ion Accelerator Facility), which is capable of measuring both horizontal and vertical profiles by simply changing the E-field. Its installation space is reduced to be only half comparing to that of a conventional IPM. A ceramic substrate PCB coated with copper anodes is used to collect electrons after the MCP output. A 64-channel data acquisition system based on the trans-impedance amplifier, ADC, FPGA and ARM is developed as well with a fast response of 1 MHz. To decrease the trajectory distortion during the electron collection, a bipolar magnet with a square shape is designed to correct the horizontal or vertical profile errors. In summer 2021, the compact IPM had been tested in Low Energy Accelerator Facility at IMP (LEAF, IMP) with the 0.5 MeV/u carbon beams. It obtains the profiles successfully in both directions. And the comparison between an upstream wire scanner and the IPM has also been done. Additionally, the magnet field shows a significant suppression effect during the signal collection. Despite some minor discrepancies, the beam experiments show a reasonable and good result.

The KOMAC (Korea Multi-purpose Accelerator Complex) has operated 100-MeV proton linear accelerator and provide high flux proton beam at the TR103, a general purpose irradiation facility. To uniformly irradiate the sample with protons, it is important to confirm the beam profile uniformity through the quality assurance (QA) process. Recently, for real-time and in-situ proton beam profile monitoring at the TR103, P43 phosphor screen and TE-cooled CMOS camera were introduced and tested. The camera captured images of the emitted light as protons with energy of 15, 42, 100 MeV were incident. A software for selecting beam profile image and post-processing of image data such as background subtraction, image smoothing, geometrical correction, selecting Region Of Interest (ROI) and X-Y coordination was developed using Python. Measured beam profiles using phosphor screen and cooled camera were compared to Gafchromic film. The linearity between light output and beam flux were measured. In this study, we will discuss the test results of proton beam profile measurement using phosphor screen and TE-cooled CMOS camera for introduction to quality assurance process at the TR103.

Large accelerator systems typically include many individually powered electromagnets. An important activity prior to commissioning with beam is verifying that the polarity of the installed magnets matches the design lattice. In the present work, we motivate the measurement of magnet polarity in a manner that is electrically safe, by measuring the magnetic remanence of iron yokes of normal conducting electromagnets. This has been used to confirm the polarities of iron-dominated dipole and quadrupole electromagnets at the Linac Extension Area at the Advanced Photon Source.

A new synchrotron light monitor has been tested for the booster synchrotron of the Advanced Photon Source. Visible light synchrotron radiation is collected by a mirror on a path tangential to the electron beam orbit, and directed to an optical imaging system and camera. This is planned to be a non-intercepting, transverse beam-size monitor even with the higher stored beam charges (~17 nC) needed for the Advanced Photon Source Upgrade. In the present work, we describe the present synchrotron radiation diagnostic layout. An analysis of the synchrotron radiation power on the mirror, the optical layout with components, and features of the control system will be presented.

WEP018 Simulation of Oscillating Arm Wire Monitor Mechanics Driven by a Stepper Motor 373
 
  • R. Dölling
    PSI, Villigen PSI, Switzerland
  
  The present oscillating arm wire monitors at HIPA operate with wire speeds of 0.75 m/s. Based on basic dynamic simulations of mechanics and motor, we discuss possible variants of this design using stepper motors in open loop control. The results suggest that 4 m/s can be reached with sufficient position resolution, when using a predefined step sequence customized to the mechanics. This speed should be sufficient to measure the full proton beam current in the injection line.

  To confirm the use of Fixed Field Alternating gradient accelerator (FFA) as a high power pulsed neutron spallation source, a prototype called FETS-FFA is studied at Rutherford Laboratory (RAL). A single Wire Scanner Monitor (WSM) is planned to be used to measure a beam position and a beam profile in the ring. One of the concerns of this monitor is the thermal damage on the Carbon Nano Tube (CNT) wire due to high energy deposition of low energy proton beam in FETS-FFA (3 - 12 MeV). Furthermore, to measure a beam profile during beam acceleration in the ring, a diameter of CNT wire needs to be smaller than the orbit displacements in turns. To confirm whether a single WSM is suitable for FETS-FFA ring, two different beam tests were performed at RAL and at the Institute for Integrated Radiation and Nuclear Science, Kyoto University (KURNS). Both measurements demonstrated that the single WSM is applicable for FETS-FFA ring if the diameter of CNT is smaller than the orbit separation in turns. In this paper, the detail of the design study of the single WSM as well as the performance tests are presented.

WEP020 Performance Evaluation of GAGG+ and Tungsten Carbide Blades in an X-ray Pinhole Camera 382
 
  • S.B. Burholt, L. Bobbpresenter, N. Vitoratou
    DLS, Harwell, United Kingdom
  
  At Diamond Light Source two X-ray pinhole cameras are used to measure the transverse profile of the 3 GeV electron beam. The current pinhole assembly is formed using tungsten blades with chemically etched shims to produce a 25 µm x 25 µm aperture and the imager incorporates a 0.2 mm LuAG:Ce scintillator. Tungsten carbide is a machinable high-Z material which at millimetre thicknesses is opaque to X-rays. With a slight change in pinhole design, similar to that already in place at the ESRF, tungsten carbide blades could offer a well-controlled aperture size for the pinhole camera with simpler assembly. Further to this, improvements to the photon yield of scintillators mean that the new scintillator GAGG+ has an almost two fold increase in yield compared to the current LuAG: Ce scintillator. An evaluation of the tungsten carbide blades and GAGG+ scintillator is presented.

WEP021 100Hz X-ray Beam Profile Measurements from a Transmissive CVD Diamond Detector 387

  A non-destructive CVD diamond X-ray beam imaging monitor has been developed for synchrotron beamlines. The device can be permanently installed in the X-ray beam path and is capable of transmissively imaging the beam profile at 100 frames per second. The response of this transmissive detector at this imaging rate is compared to synchronously acquired images using a destructive fluorescent screen. It is shown that beam position, size, and intensity measurements can be obtained with minimal disturbance to the transmitted X-ray beam. This functionality is beneficial to synchrotron beamlines as it enables them to monitor the X-ray beam focal size and position in real-time, during user experiments. This is a key enabling technology that would enable live beam size feedback, keeping the beamline’s focusing optics optimised at all times. Ground vibrations (10-20Hz) can cause movement of focusing optics and beamline mirrors, which disturb the X-ray beam and reduce the ultimate quality of the sample-point beam. This instrument can detect this beam motion, enabling the source to be more easily determined and mitigations to be put in place.

WEP022 Target Multiwire for the Fermilab Booster Neutrino Beamline 392
 
  • R.M. Prokop
    Fermilab, Batavia, Illinois, USA
  
  Funding: This work was supported by the U.S. Department of Energy under contract No. DE-AC02-07CH11359.
The Booster Neutrino Beamline experiment requested a new secondary electron emission multiwire profile monitor installation. The device had to be durable in high radiation conditions and mounted within a large 10 foot airtight steel fixture for installation near the beam target. Previous iterations of multiwire suffered radiation damage to both the connectors and wires. To ensure accurate horizontal and vertical beam profile measurements, an updated design was proposed, designed, and constructed. The new BNB multiwire utilizes 3 mil diameter gold-plated tungsten sense wires soldered to vertical and horizontal Alumina-96 ceramic planes, 50 wires per plane. Radiation hard Kapton insulated 30 gauge wires carry the output signals. Profiles are readout through charge integrator scanner electronics. This paper will detail the design and functionality of the BNB target multiwire and present relevant beam profile data.

The current program at Fermilab involves the construction of a new superconducting linear accelerator (LINAC) to replace the existing warm version. The new LINAC, together with other planned improvements, is in support of proton beam intensities in the Main Injector (MI) that will exceed 2 MW. Measuring the transverse profiles of these high intensity beams in a ring requires non-invasive techniques. The MI uses ionization profile monitors as its only profile system. An alternative technique involves measuring the deflection of a probe beam of electrons with a trajectory perpendicular to the proton beam. This type of device was installed in MI and initial studies of it have been previously presented. This paper will present the status and recent studies of the device utilizing different techniques.

The Proton Improvement Plan - II (PIP-II) is a new linear accelerator (LINAC) complex being built at Fermilab. It is based on superconducting radiofrequency cavities and will accelerate H− ions to 800 MeV kinetic energy before injection into the existing Booster ring. Measurements of the profile of the beam along the LINAC must be done by non-intercepting methods due to the superconducting cavities. The method chosen is photoionization of a small number of H− by a focused infrared laser, aka laserwire. The number of ionized electrons is measured as a function of laser position within the H− beam. To aid in the design of the collection mechanism, a simulation was written in MATLAB with input from the commercial electromagnetic simulation, CST. This simulation calculates the number and positions of the liberated electrons and tracks them through the magnetic collection and H− beam fields to the collection point. Results from this simulation for various points along the LINAC will be shown.

WEP025 A Study of the Gain of Microchannel Plates in the Ionization Profile Monitors at Fermilab 405

One of the on-going issues with the use of microchannel plates (MCP) in the ionization profile monitors (IPM) at Fermilab is the significant decrease in gain over time. There are several possible issues that can cause this. Historically, the assumption has been that this is aging, where the secondary emission yield (SEY) of the pore surface changes after some amount of extracted charge. Recent literature searches have brought to light the possibility that this is an initial ’scrubbing’ effect whereby adsorbed gasses are removed from the MCP pores by the removal of charge from the MCP. This paper discusses the results of studies conducted on the IPMs in the Main Injector at Fermilab.

  Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661, the State of Michigan and Michigan State University.
We report on the status of work on a non-invasive profile monitor under development for use at the Facility for Rare Isotope Beams (FRIB), a heavy-ion LINAC which produces high-intensity, multi-charge state beams. The measurement will be made by collecting photons generated at the interaction point of the beam and a collimated molecular gas curtain. These photons will be collected with an intensified camera system, generating a two dimensional image and allowing for measurements of profile, beam halo, and other properties more prevalent at specific locations of interest, such as charge state spread after folding segment bends. Included will be ongoing design specifications, simulation results, and discussion of measurement techniques for acquiring signal from the device.

The Los Alamos Neutron Science Center (LANSCE) is currently upgrading the existing emittance stations with a high-density instrumentation system for emittance measurements in the low energy beam transport region. Emittance measurements were obtained using obsolete legacy equipment. For motion control a switching station with a mechanical mux to switch actuators was used. This caused a single point of failure for all emittance stations and is becoming increasingly unreliable. For data acquisition, two sets of signal conditioning and digitizers were employed and had to be shared between 7 emittance stations. Physical cable swapping was necessary when taking measurements from station to station. A system was developed using dedicated Quad Actuator Controller (QAC) chassis, capable of driving four (4) actuators, and dedicated data acquisition (DAQ) chassis capable of signal conditioning and digitizing up to 80 channels simultaneously. Details of the system development are presented.

High density instrumentation has been developed to upgrade wire scanner beam diagnostic capability in all areas downstream of the Coupled Cavity LINAC (CCL). Transverse beam profile measurements were originally obtained using legacy electronics known as Computer Automated Measurement and Control (CAMAC) crates. CAMAC has become obsolete, and a new wire scanner diagnostic system was developed as a replacement. With high wire scanner device density located in each area, instrumentation was developed to meet that need along with the ability to interface with legacy open-loop controlled actuators and be forward compatible with upgraded closed-loop systems. A high-density system was developed using a Quad Actuator Controller (QAC) and Data Acquisition (DAQ) chassis that pair together using a sequencer when taking measurements. Software improvements were also made, allowing for full waveform functionality that was previously unavailable. Deployment of 52 wire scanner locations in 2022 increased device availability and functionality across the facility. Hardware and software design details along with results from accelerator beam measurements are presented.

  Nusano is developing a 50 MeV alpha (4He++) particle accelerator*, primarily to produce medical radionuclides. The accelerator produces an average current of 3 mAe with 20 mAe average macro pulse current. This results in an average beam power of 75 kW, and an average beam power within the macro pulse of 500 kW. The beam profile at the exit of the DTL is approximately gaussian with a diameter (FWHM) of about 3 mm. Designing diagnostics for this beam is challenging, as any diagnostics that intercept beam will receive a very high heat load. A BIFM (Beam Induced Fluorescence Monitor) is being developed to measure beam profiles. Nitrogen gas is leaked into the beamline. Excitation of the nitrogen by beam particles is captured using an image intensifier. The signal generated is directly proportional to the beam current. A prototype system has been constructed and tested on a lower intensity alpha beam. First results indicate we can measure beam profile to a 100 µm accuracy. Production system is currently being designed.
* The Nusano accelerator can also accelerate 2H+, 3He++, 6Li3+, 7Li3+, and a few other heavier ions.

We describe the Image Acquisition system for the Injection Dump. This system visualizes the different beamlets, on the vacuum window after the H− beam is stripped of its electrons by two stripper foils. One beamlet is from H− with its electrons stripped by the first foil and the second beamlet has it final electron stripped by the second foil. We used the PXI platform to implement the data-acquisition including timing decoder. We describe the hardware and software for the system. We use a standard non-radhard GigE camera to acquire the image from the luminescent coating on the dump vacuum window. To lower the radiation damage to the camera, we shield it with stainless steel blocks. We present radiation measurements before and after shielding. We also show the radiation damage over time to estimate the camera’s lifetime.

The Mu2E experiment will measure the ratio of the rate of the neutrinoless, coherent conversion of muons into electrons as a measure of Charged Lepton Flavor Violation. As part of the Mu2E experiment, a proton storage ring, called the Delivery Ring, will utilize resonant extraction to slow-spill protons to the experiment. To regulate and optimize the Delivery Ring resonant extraction process, a fast tune measurement scheme will be required. This Mu2E tune meter will measure the average tune and the tune spectrum, in multiple time slices, through the entire resonant extraction cycle of nominally 43 msec. The Mu2E tune meter utilizes vertical and horizontal 21.4 MHz Schottky detector resonant pickups, taken from the decommissioned Tevatron, as well as its receiver electronics. This paper will present the design of this Schottky tune meter as well as tune measurements from the Mu2E Delivery Ring.

  Schottky spectra can be strongly affected by collective effects, in particular those arising from beam-coupling impedance when a large number of bunch charges are involved. In such conditions, the direct interpretation of the measured spectra becomes difficult, which prevents the extraction of beam and machine parameters in the same way as is usually done for lower bunch charges. Since no theory is yet directly applicable to predict the impact of impedance on such spectra, we use here time-domain, macro-particle simulations and apply a semi-analytical method to compute the Schottky spectrum for various machine and beam conditions, such as the ones found at the Large Hadron Collider. A simple longitudinal resonator-like impedance model is introduced in the simulations and its effect studied in different configurations, allowing preliminary interpretations of the impact of longitudinal impedance on Schottky spectra.

  Schottky signals are used for non-invasive beam diagnostics as they contain information on various beam and machine parameters. The instantaneous Schottky signal is, however, only a single realisation of a random process, implicitly depending on the discrete distribution of synchrotron and betatron amplitudes and phases among the particles. To estimate the expected value of the Schottky power spectrum, and reveal the inner structure of the Bessel satellites described by the theory, the averaging of instantaneous Schottky spectra is required. This study describes this procedure quantitatively by analysing the statistical properties of the Schottky signals, including the expected value and variance of Schottky power spectra. Furthermore, we investigate how these quantities evolve with the number of particles in the bunch, the observed harmonic of the revolution frequency, the distribution of synchrotron oscillation amplitudes, and the bunch profile. The theoretical findings are compared against macro-particle simulations as well as Monte Carlo computations.

  There is a plan in the Canadian Light Source (CLS) to replace the current Linac with a new one from Research Instruments GmbH in mid-2024. The first straight section of LTB (Linac-To-Booster) was upgraded to have two BPMs with a 4.79m drift between them, and two phosphor screens were replaced by YAG screens. A new BPM and a YAG-based screen station upgraded the following 90-degree achromat beamline. These upgrades help us to measure the current and future Linac beam parameters, including the beam twiss parameters, energy, and energy spread. In this paper, we discussed how we could use these three BPMs for non-destructive energy measurement, which will be a part of the active energy correction system.

  A high-sensitivity tune measurement system have been developed for the Booster Ring (BRing) and Spectrometer Ring (SRing) of the High-Intensity heavy-ion Accelerator Facility (HIAF). The beam signal induced by the BPM bipolar plate is amplified by the measurement system via a preamplifier, and then fed through the direct diode detection circuit to the spectrometer for Fourier analysis to calculate the tune fraction. Simulation results show a signal-to-noise ratio of approximately 50 dB without beam excitation. The new system is more sensitive to the detection of tuned fractions than conventional electronic storage ring tuning measurement systems and is simple and does not require beam excitation. This paper presents the design of HIAF tune measurement system, especially on front-end electronics design and the simulation results.

  In recent decades, the high-gain free-electron lasers (FELs) based on linear accelerator has been successfully developed around the world. Advanced beam diagnostics and feedback technology is one of the key factors to further improve the performance of such facilities. Both the beam position deviation and orbit tilt will weaken the interaction between electron beam and photon beam in the undulator, and affected the FEL radiation performance severely. According to the physical requirements of the SHINE, this paper proposes a method based on the measurement results of a single cavity BPM, which can simultaneously achieve the in-suit measurement of beam position deviation and orbit tilt, thus opening up a new way to improve the efficiency of FEL radiation. The working principle, the development of the verification prototype and the preliminary beam experiments will also be presented in this paper. Under the bunch charge of 100 pC, the beam experiment results show that the prototype has a resolution of better than 13.3¿rad for the beam orbit tilt measurement, which can be applied to the SHINE after optimization.

  In order to improve the operating performance of the particle accelerator, it is better to develop a toolkits to monitor and analyze the sub-health state of the facility in addition to ensuring the stability of basic parameters such as beam current, life, transverse size, longitudinal length and orbit. The 3D bunch-by-bunch position measurement system combined with cluster analysis is a feasible solution for this requirement. HOTCAP is a general solution, which is based on high-speed oscilloscope and developed by SSRF, can deliver charge and absolute 3D position information bunch-by-bunch. Clustering analysis is a method for multidimensional data with complex structure. The data can be aggregated and discover the dependencies between data items. After the SSRF bunch-by-bunch measurement system is put into operation, the data of injection and steady-state operation are continuously accumulated. From it, many information including 3D positions, 3D tunes, filling pattern, refilled charge and the 3D damping times can be extracted. In this paper, based on the operational data of SSRF and the cluster analysis, operational status of the storage ring and injector is evaluated.

The Los Alamos Neutron Science Center’s (LANSCE) Accelerator Operations and Technology division group executed a project that implemented a new analog front-end card (AFE) for their wire scanner’s Data Acquisition (DAQ) system. The AFE accommodates the signal amplification and noise reduction needed to acquire essential measurement data for beam diagnostics for the LANSCE accelerator. Wire Scanners are electro-mechanical beam interceptive devices that provide cross-sectional beam profile measurement data fitted to a Gaussian distribution that provides beam shape and position information. The beam operators use the beam shape and position information to adjust parameters such as acceleration, steering and focus on delivering an optimized beam to all targets. The project implemented software and hardware that eliminated the dependency on legacy systems and consolidated various AFE designs for diagnostics systems into a single design with 11 gain settings ranging from 100 nA to 40 mA at 10 V full scale to accommodate future applications on other diagnostic systems.

  The CW electron accelerator ELBE is in operation for more than two decades. The timing system has been patched several times in order to meet changing requirements. In 2019 the development of a new timing system based on Micro Research Finland Hardware has been started which is designed to unify the heterogeneous structure and to replace obsolete components. In spring 2023 the development of the software has been accomplished, which included the mapping of operation mode and different complex beam patterns onto the capabilities of the commercial platform. The system generates complex beam patterns from single pulse, to macro pulse and 26 MHz cw operation including special triggers for diagnostics and machine subsystems. The contribution will describe the path from requirements to development and commissioning of the new timing system at ELBE.

  In the course of modernization of camera based imaging and image analysis for accelerator hardware and beam control at the ELSA facility, a distributed image processing approach was implemented, called FGrabbit. We utilize the RabbitMQ message broker to share the high data throughput from image acquisition, processing, analysis, display and storage between different work stations to achieve an optimum efficacy of the involved hardware. Re-calibration of already deployed beam profile monitors using machine vision algorithms allow us to perform qualitative beam photometry measurements to obtain beam sizes and dynamics with good precision. We describe the robustness of the calibration, image acquisition and processing and present the architecture and applications, such as the programming- and web-interface for machine operators and developers.

  It has been more than ten years since HPAD (Hybrid Pixel Array Detectors) had been widely utilized as X-ray diffraction and imaging detectors. Due to limitations of the fabrication process, most HPADs are made with monolithic sensor and tiled readout ICs. In conventional HPAD, there were so-called ¿inter-chip pixels¿ on the edges of readout ICs. These inter-chip pixels have 1.5 times or even wider width and/or height than non-inter-chip pixels. We have successfully dealt with this inter-chip pixel problem by use of re-distribution layer on the Silicon sensor. So, in our new detector, non-uniformity in a single sensor module is eliminated. This new detector is designed based on UFXC32k IC* designed by AGH University of Science and Technology and named XSPA Detector Series. XSPA Series are aiming not only for X-ray imaging but also for time-resolved X-ray measurements. Thanks to its high count-rate and fast operation capability combined with our high data throughput backend circuits, XSPA Series are capable of up to 56 kfps full-frame operation. We are working on beam position and intensity monitor based on the XSPA Series. Results from its preliminary tests will be presented.
