The new LCLS-II facility at the SLAC National Accelerator Laboratory is a significant addition to the LCLS-I FEL, designed to dramatically decrease data acquisition time by providing high repetition rate over a broad energy range. The new design consisting of a CW superconducting linac with bunch repetition rates of up to one MHz and beam power of several hundred kilowatts requires major enhancements to the LCLS-I controls system. LCLS-II will retain the system architecture based on EPICS while implementing additional technologies to meet the new requirements. This includes new designs for SC LLRF, timing system to allow MHz operation, data acquisition electronics for the beam position monitors and other beam diagnostic systems, and a new beam-based feedback facility. The high beam rate and power also necessitate faster beam abort mechanisms, requiring enhanced machine and personnel protection systems as well as a new radiation containment system. This paper will present an overview of the LCLS-II controls and discuss the design status of the critical systems including the development of a general purpose electronic system to serve as a common platform for several applications.

  After the long shut down of 2013-2014, the LHC energy will be pushed toward 7 TeV. In this range of energy, the main magnets will enter a new regime. For this reason, this paper will present a detailed study of the performance of the FiDeL model that could be critical for the operation in 2015. In particular this paper will study the saturation component and its precision in the model, together with the hysteresis error. The effect of these two components and their errors on the beta-beating is also given. Furthermore, an estimate of the dynamic effects visible in the tune and chromaticity will be presented for the 7 TeV operation.

  The MYRRHA project currently under development at Mol, Belgium, is an Accelerator Driven System expected to be operational in 2023 with the primary purpose to study the feasibility of efficiently transmuting nuclear waste products into isotopes with much shorter lifetimes. The reactor, which is expected to have a thermal power of ~70 MW, may be operated in subcritical mode when fed by spallation neutrons obtained from a 600 MeV superconducting proton linac hitting a Liquid Pb-Bi eutectic (LBE) target with an average current of 4 mA. The challenging aspect of the MYRRHA linac resides in its very high availability (close to 100%) with a Mean Time Between Failure expected to be higher than 250 hours. This paper presents the strategic approach taken during the design of the linac and its foreseen operation to fulfill this stringent requirement. In particular we will describe the concept of a beam dynamics based control system also called Virtual Accelerator which will be mandatory for the operation of such linac.

The Compton back-scattering based compact X-ray source ThomX is under construction in LAL/IN2P3, CNRS, France. This machine will serve as a demonstrator in producing up to 1013 ph/s for imaging and cultural heritage recovery. The high level applications of the ThomX machine for the future commissioning and operations are being developed using Matlab Middle Layer (MML) which is broadly used in the modern synchrotron light sources. In this article, we report the nearest progresses of high level applications of the ThomX machine, and present the nonlinear response matrices to correct the tune, chromaticity and orbit, and the algorithm to correct the orbit in the transfer line.

    ELSA, Bonn, Germany
 
  The electron stretcher facility ELSA serves external hadron physics experiments with a beam of unpolarized and polarized electrons of up to 3.2 GeV energy. Its in house developed control system is able to provide real time beam diagnostics as well as steering tasks in one homogeneous environment. The existing archive engine, a simple application logging parameter changes to a file storage, was unable to cope with the rising amount of parameter updates per second. Therefore a new storage system based on the non-relational database system hypertable has been introduced. It is capable of storing huge amounts of data to distributed storage systems, thus being able to handle the recording of every parameter change at any given time. The data can be read back with low latency to a newly developed graphical data browser using a C++ interface. This contribution will give details on the setup and performance of the history storage engine on top of hypertable.

  Based on the Bunch Phase Timing System (BuTiS)* local analog radio frequency reference signals (RF references) like the particle revolution frequency and their multiple harmonics will be generated. These references are used to control the phase of the accelerator cavities to altering harmonics of the bunch revolution frequency. Delay or phase shifts from the FAIR-Center to references at the BuTiS endpoints are already compensated by the BuTiS receivers. Phase shifts from the RF reference generators to LLRF electronics can be compensated by controlling the output phases of the DDS modules of the RF references. However phase shift delays of multiple harmonics at the same interconnecting electrical path are not identical at the same time. Configurable electronics** manage phase calibration of the RF references to their endpoints. Calibration may depend on frequency and harmonic of the RF reference, aging as well as on thermal effects. The electrical length and impedance of interconnecting cables for phase control loops can be compensated. This is an important feature, in particular if control loops are switched between different harmonic frequencies.

  The Frankfurt Neutron Source at the Stern- Gerlach Zentrum (FRANZ) is a multi-purpose facility for experiments related to accelerator development and nuclear astrophysics. A 200 mA proton beam will produce a neutron flux by use of the reaction 7Li(p, n)7Be. To study the reliability and performance of the accelerator an effective and powerful control system will be needed. A small ion source was used for the first performance test of the control system. The design of the control loop algorithm for the High Current proton source will be discussed. Physical data routinely taken by the control system are compared with manual measurements.

The MicroTCA.4 crate standard is a powerful electronic platform for digital and analog signal processing. Besides its hardware modularity, it is the software reliability and flexibility as well as the easy integration into existing software infrastructures that will drive the widespread adoption of this new standard. The DESY MicroTCA.4 User tool kit (MTCA4U) provides drivers, and a C++ API for accessing the MicroTCA.4 devices and interfacing to the control system. The PCIexpress driver is universal for basic access to all devices developed at DESY. Modularity and expandability allow to generate device-specific drivers with a minimum of code, inheriting the functionality of the base driver. A C++ API allows convenient access to all device registers by name, using mapping information which is automatically generated when building the firmware. A graphical user interface allows direct read and write access to the device, including plotting functionality for recorded raw data. Higher level applications will provide callback functions for easy integration into control systems, while keeping the application code independent from the actual control system in use.

  We have upgraded the accelerator control network system for SuperKEKB, the upgrade of the KEKB asymmetric energy e+e collider for the next generation B-factory experiment in Japan. For SuperKEKB, the accelerator control network system with the higher performance of the wider bandwidth data transfer, and more reliable and redundant configuration, is required, to ensure the robust operations under the 40 times higher luminosity. We install the 10 gigabit Ethernet (10GbE) network switches for the wider network bandwidth and optical cables to construct the redundant network. We reconfigure the network design to connect the accelerator control network and the KEK laboratory network to enhance the security. For the beamline construction and the accelerator components maintenance, we install the new wireless network system consists with the Leaky Coaxial (LCX) cable antennas and collinear antennas, which have good radiation hardness of >1MGy, into the 3 km circumference accelerator tunnel. In this paper, we describe the design and current status of the SuperKEKB accelerator control network system.

  The control system of Accelerator Driven Sub-critical System (ADS) should be a high-availability (HA) system with fault tolerant architecture, due to the potential utilizations of the ADS, such as separating and transmuting irradiated nuclear fuel. This paper discusses the HA software architecture of ADS control system which mainly composed by four softwares, which are 1) low floor communication and control system–-EPICS [1], 2) hierarchal programming framework of the accelerator–XAL [2], 3) monitoring and operating large scale control systems–Control System Studio (CSS) [1], 4) data storage and service infrastructure–HA database and server cluster. In addition, the recent development of ADS control system is briefly introduced in this paper.

  Power subsystem has been upgraded for energy improvement of the BEPCII Linac. As a result, new control system was in need. This paper proposes the designing and implementation about the power-supply control system. There are 156 sets of power supply in the system, which is divided into 6 parts, according to function. The control system is intended to make operations more convenient and efficient in beam regulation, which provides functions to meet such situations, like single regulation; restore the beam configures from data files; one-button to switch the electronic polarity (E-/E+). What’s more, the software provides a method of slow-change to protect the power supplies, when value change is too steep. Compare to the old system, this new software is more maintainable and extensible. This software is based on Qt, the GUI library for C++, and connects to the control box through the EPICS (Experimental Physics and Industrial Control System). The whole 156 sets of power supply are controlled by control boxes, which is ARM+FPGA (CPLD)-Structure front-end IO. This control system has assembled in BEPCII LINAC in September, which plays an important part in the following working.

  The accelerator (ACC) is the first step of the accelerator driven system (ADS). A high power continuous wave ACC is required for ADS applications. An essential aspect of ACC is beam availability. It must be an order of magnitude better than current best systems. High availability is achieved by fault tolerance and redundancy of the ACC. Three factors play a key role here: use of components in a high MTBF regime, parallel and serial redundancy of components, ability to repair failing elements. In terms of ACC controls system (CS) EPICS and Linux is chosen as proven technology. High availability will be achieved through making parts of the CS redundant. Subsystems shall be redundant by design. If failure of a subsystem is detected, pre-defined scenarios should kick-in. System model or "virtual accelerator" can be implemented to predict effects of parameter change, determine required configuration of set points for optimal performance or re-configuration in case of sub-system failure. Implementation of predictive diagnostics can harvest large amount of data created by archiving service. Prediction of failure allows for controlled shutdown as opposed to abrupt stop.

  The European Spallation Source (ESS) project is starting the construction of buildings June 2014. When the access to linac tunnel and gallery building is ready, the commissioning of the first sections of the accelerator starts. A proper operation of the machine relies on the services provided by different infrastructure systems (water cooling, electrical power system, ventilation, etc.) These systems will be used long before beam operation starts and need to be operated via the Integrated Control System (ICS) from the Control Room. Due to the number and variety of these systems, their heterogeneous characteristics and the different teams of designers, the integration process into ICS is challenging. Experience in other facilities [2,3] shows that a late integration produces higher maintenance and operation costs, and even impact on the reliability of the machine. This paper presents the strategy developed by two partners, the Controls and Conventional Facilities Division (CF). It is planned to capture the requirements for the interfaces and to ensure an early integration of Infrastructure Systems into the EPICS environment. First results of this approach are shown for some systems.

  The European Spallation Source (ESS) is an accelerator- driven neutron spallation source. The Integrated Controls Systems (ICS) is responsible for providing control and mon- itoring for all parts of the machine (accelerator, target, neu- tron scattering systems and conventional facilities) [1]. A large number of applications have been identified across all parts of the facility where PLCs will be used: cryogenics, vacuum, water-cooling, power systems, safety and protec- tion systems. The Controls Division at ESS is deploying a PLC Test Bench. The motivation is to evaluate different technologies, to test PLCs and their integration into EPICS, to prototype control systems and use the test bench as PLC software development platform. This report defines the ar- chitecture of this infrastructure. The first stage to procure a first set of hardware and to perform initial tests has already been finished, consisting of a comparison between the per- formance of the s7plc EPICS driver and the Modbus EPICS driver. The results of these tests are discussed and future plans for this infrastructure are presented.

Turkish Accelerator and Radiation Laboratory in Ankara (TARLA) is a Free Electron Laser (FEL) facility designed to generate Free Electron Laser (FEL) in 3-250 um wavelength range, based on four 9-cell Super Conducting (SC) cavities with 10MeV/m gradient each. TARLA electron gun has been in operation since 2012. Control system studies with EPICS are being run as test stand control and permanent system and each are running as individual projects while test stand control is in stable revision. The aim of the system design is to create a fast and reliable control system which is easy to operate and extensible for future upgrades/improvements. Now, the development and implementation of control system is ongoing in a parallel manner with the rest of the accelerator as well as the architectural design, In this study, the permanent and the test stand control systems of TARLA will be discussed.

With the installation and commissioning of the third accelerating cryomodule in summer of 2014 the first phase of the radioactive ion beams postaccelerator ReA at National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU) will be completed. ReA was integrated in 2013 into the Coupled Cyclotron Facility providing unique low-energy rare isotope beams. After the fast rare isotopes are stopped in a gas stopping system, mass separated and their charge state boosted in an Electron Beam Ion Trap (EBIT), the ions are reaccelerated in a compact superconducting (SC) LINAC. For rare isotope operations, the LINAC is pre-tuned using stable pilot beams with a similar mass to charge ratio as the rare isotope beams and consequently the system is scaled. Scaling steps of up to 5\% are needed to change to the radioactive beams. To preserve the stringent beam characteristic on the experimental end station a precise online model is required. We will present the status of this online model.

Los Alamos National Laboratory (LANL) has defined a signature science facility Matter-Radiation Interactions in Extremes (MaRIE) that builds on the existing Los Alamos Neutron Science Center (LANSCE) facility to provide unique experimental tools to develop next-generation materials that will perform predictably and on demand for currently unattainable lifetimes in extreme environments. At its core a new 42 keV XFEL will be coupled with a MW class proton accelerator. While the larger MaRIE project is working on a pre-conceptual design a smaller LANL team is working on an injector test-stand to be constructed at LANL in the course of preparation for MaRIE. The test stand will consist of a photo injector and an initial accelerating section with a bunch compression section. The goal of this facility will be to carry out studies that will determine optimal design parameters for the prototype injector, and to facilitate a direct demonstration of the required beam characteristics for MaRIE. This paper will give a brief overview of the proposed MaRIE facility and present the conceptual design for the injector test stand with the focus on the instrumentation and control system.

  A comprehensive set of graphical user interfaces is being developed for the drive laser of the Advanced Superconducting Test Accelerator (ASTA) facility at Fermilab. These interfaces have been designed in Synoptic, a Java-based GUI development platform with credential-dependent access to the Fermilab accelerator controls network. Such implementation facilitates the user's ability to monitor and control many aspects of the drive laser system in an intuitive environment, as well as timely updates on the part of the developers made necessary by the evolving drive laser system. Furthermore, the current interface hierarchy readily allows integration into the larger pool of Synoptic applications being developed for other subsystems at ASTA.

  Taiwan Photon Source (TPS) is a new 3-GeV ring under construction at NSRRC in Taiwan. There are hundreds of magnets placed on girders that must be aligned correctly to keep the electronic beam in the desire orbit. Due to the reasons of manpower, set up time, accuracy of adjustment, deformation of the floor, and limited space, an auto-alignment girder control system was designed to meet this requirement. The auto-alignment test was completed with one double-bend cell at NSRRC. The Auto-alignment process will be tested with some sections of magnet girders to confirm the control system and the algorithm in the TPS. The status and test results will be described in this paper.
