	The Facility for Antiproton and Ion Research FAIR, in Darmstadt Germany, will be one of the largest accelerator laboratories worldwide. The Superconducting FRagment Separator (Super-FRS)* is one of its main components. The Super-FRS can produce, separate and deliver high-energy radioactive beams with intensities up to 1e11 ions/s, covering projectiles from protons up to uranium and it can be used as an independent experimental device. The Gas Electron Multiplier-based Time Projection Chambers (GEM-TPC) in twin configuration is a newly developed beam tracking detector capable of providing spatial resolution of less than 1 mm with a tracking efficiency close to 100% at 1 MHz counting rate. The GEM-TPC (HGB4) was tested at the FRagment Separator (FRS), with 238U beam at 850 MeV/u. A new clusterization method was developed, for the first time and used for an analysis. This method allowed to access to waveforms of each strip signal within a single trigger in an event-by-event basis. The procedures involved in this method will be shown in details. * H.Geissel et al., The Super-FRS project at GSI, Nucl. Instr. and Meth. in Phys., vol. B204, pp. 71-85, 2003.

MOPOPT038	Development of Button BPM Electronics for the Bunch by Bunch Feedback System of 4GSR	feedback, electron, storage-ring, booster	332
	S.W. Jang KUS, Sejong, Republic of Korea
	With the advent of the fourth-generation storage ring, the size of the vertical emittance of the electron beam is expected to be about 100 times smaller than that of the existing generation. In line with the development of accelerator performance, the resolution of the beam position monitor(BPM) should also be further improved, and it can be provide a more stable and uniform beam to end station users through improved bunch by bunch(BbB) feedback system compared to a system called turn by turn or fast feedback. A developed BPM electronics for BbB feedback will be installed in Bessy II booster ring at HZB Research Institute in Germany. BbB feedback BPM electronics with an improved three button BPMs will be used to measure beam position resolution and calculate an information for BbB feedback and then it will apply to the BbB feedback system. In this proceeding, we will describe the development of an upgraded beam position monitor and BPM electronics for BbB feedback.

	During the Long Shutdown 2 (LS2, 2019-2020), the CERN accelerator complex has undergone major upgrades, mainly in preparation for the High-Luminosity (HL) LHC era, the ultimate capacity for its physics production. Therefore, several novel equipment and systems were designed and deployed throughout the accelerator complex. To comply with the radiation level specifications and avoid machine downtime due to radiation effects, the electronics systems exposed to radiation need to follow Radiation Hardness Assurance (RHA) methodologies developed and validated by the Radiation to Electronics (R2E) project at CERN. However, the establishment of such procedures is not yet fully implemented in the LHC injector chain, and some R2E failures were detected in the SPS during the 2021 operation. This work is devoted to describing and analysing the R2E failures and their impact on operation, in the context of the related radiation levels and equipment sensitivity.

TUOXGD2	Wireless IoT in Particle Accelerators: A Proof of Concept with the IoT Radiation Monitor at CERN	radiation, network, monitoring, electron	772
	S. Danzeca, A.J. Cass, A. Masi, R. Sierra, A. Zimmaro CERN, Meyrin, Switzerland
	The Internet of Things (IoT) is an ecosystem of web-enabled "smart devices" that integrates sensors and communication hardware to collect, send and act on data acquired from the surrounding environment. Use of the IoT in particle accelerators is not new, with accelerator systems long having been connected to the network to retrieve, send and analyse data. What has been missing is the IoT concept of "smart devices" and above all wireless connectivity. We report here on the advantages of using a particular IoT technology, LoRa, for the deployment of wireless radiation monitors within the CERN particle accelerator complex. IoT Radiation Monitors have been developed as a result of growing demand for radiation measurements where standard infrastructure is not available. As a radiation-tolerant device, the IoT Radiation Monitor is a powerful "eye" for observing the real-time radiation levels in the CERN accelerators. We describe here the technologies used for the project and the various advantages their deployment offers in a particle accelerator environment. This opens up the possibility for the deployment of heterogeneous implementations that would otherwise have been impractical.

TUPOPT067	Development of a Trigger Distribution System Based on MicroTCA.4	timing, electron, FPGA, controls	1171
	H. Maesaka, N. Hosoda, T. Inagaki, E. Iwai, T. Ohshima RIKEN SPring-8 Center, Hyogo, Japan N. Hosoda, T. Inagaki, E. Iwai, H. Maesaka, T. Ohshima JASRI, Hyogo, Japan
	We developed a MicroTCA.4 (MTCA.4) module to generate and distribute trigger timing signals. This module has 16 LVDS inputs and 16 LVDS outputs each on the front panel and the Zone 3 connector, and 8 M-LVDS I/O’s for MTCA.4 backplane. The trigger timing of each output can be precisely adjusted with the interval of 238 MHz or 509 MHz clocks by a 24-bit counter. The timing can also be fine-tuned by ~80 ps tap delay. This module has additional 5 optical transceivers, one for receiving trigger signals from upstream and four for fanouts to downstream. A master module distributes trigger signals, trigger counts, and event data through optical links. Slave modules generate trigger output signals with appropriate delays based on the event data and the local setting for each output channel. The timing jitter was measured to be 40 ps std, which is significantly smaller than the clock period of 238 MHz or 509 MHz. This system can also distribute an alarm signal received by a slave module to take data at a faulty situation. Trigger systems with this module have been utilized in SPring-8, SACLA, and NewSUBARU and stably synchronize various accelerator components with sufficient timing accuracy.

WEPOST002	Synchrotron Radiation Impact on the FCC-ee Arcs	shielding, radiation, electron, neutron	1675
	B. Humann TU Vienna, Wien, Austria F. Cerutti, B. Humann, R. Kersevan CERN, Meyrin, Switzerland
	Synchrotron radiation (SR) emitted by electron and positrons beams represents a major loss source in high energy circular colliders, such as the lepton version of the Future Circular Collider (FCC-ee) at CERN. In particular, for the operation mode at 182.5 GeV (above the top pair threshold), its spectrum makes it penetrate well beyond the vacuum chamber walls. In order to optimize its containment, dedicated absorbers are envisaged. In this contribution we report the energy deposition studies performed with FLUKA to assess heat load, time-integrated dose, power density and particle fluence distribution in the machine components and the surrounding environment. Different choices for the absorber material were considered and shielding options for electronics were investigated. Furthermore, possible positions for the booster ring were reviewed from the radiation exposure point of view.

THPOPT009	Dependency Measurement of BPM Reading in the HLS-II Storage Ring	operation, storage-ring, feedback, electron	2580

	Beam orbit stability is essential for the operation of the storage ring based light sources. Orbit feedback systems are commonly adopted to maintain the beam on a reference orbit. However, the BPM reading could be affected by its temperature, beam current, etc, which leads to shift of the beam reference orbit. Online experiment is carried out in the HLS-II storage ring to study the dependence of the beam reference orbit on the BPM temperature and beam current. The result shows that the average change of BPM readings due to BPM temperature is about 37.4 ’m/’C horizontally and 11.5 ’m/’C vertically. The average change of BPM readings induced by beam current is about 0.27 ’m/mA horizontally and 0.20 ’m/mA vertically.

THPOTK044	Ultra-Fast Generator for Impact Ionization Triggering	pulsed-power, high-voltage, cathode, plasma	2872
	A.A. del Barrio Montañés, Y. Dutheil, T. Kramer, V. Senaj CERN, Meyrin, Switzerland M. Sack KIT, Karlsruhe, Germany
	Impact ionization triggering can be successfully applied to standard thyristors, thus boosting their dI/dt capability by up to 1000x. This groundbreaking triggering requires applying significant overvoltage on the anode-cathode of thyristor with a slew rate > 1kV/ns. Compact pulse generators based on commercial off-the-shelf (COTS) components would allow the spread of this technology into numerous applications, including fast kicker generators for particle accelerators. In our approach, the beginning of the triggering chain is a HV SiC MOS with an ultra-fast super-boosting gate driver. The super boosting of a 1.7kV rated SiC MOS allows to reduce the MOS rise time by a factor of > 25 (datasheet tr = §I{20}{ns} vs. measured tr < 800ps, resulting in an output voltage slew rate > 1kV/ns and an amplitude > 1kV. Additional boosting is obtained by a Marx generator with GaAs diodes, reaching an output voltage slew rate > 11kV/ns. The final stage will be a Marx generator with medium size thyristors triggered in impact ionization mode with sufficient voltage and current rating necessary for the triggering of a big thyristor. This paper presents the impact ionization triggering of a small size thyristor.
