| MOPMY032 | Design and Upgrade the Safety System for the SRF Electronic System at the Taiwan Photon Source | SRF, cryogenics, vacuum, storage-ring | 567 |
|
|||
| This paper presents some new designs and upgrades of a SRF interlock and electronic system. Based on the experience from Taiwan Light Source (TLS) that uses one Cornell-type superconducting cavity made by ACCEL in the storage-ring RF system [1], in the new TPS SRF system [3] home-made LLRF and SRF electronics [4] are constructed for two KEKB-type superconducting cavities [2] that are installed in the storage ring of circumference 518 m. For reliable operation of the TPS SRF system, enhanced safety functions of the system were added to improve the original SRF system in TLS. The improved functions can provide both the operators and the RF systems with a safer environment and clearer messages for trouble-shooting and malfunction status indications. | |||

| WEPMB039 | Operation Techniques for HWR1 Cryomodule | EPICS, controls, cryomodule, radiation | 2205 |
|
|||
| Control systems such as PLC and EPICS are developed for a half-wave resonator (HWR) cryomodule. PLC rack is fabricated for the HWR1 cryomodule. The PLC controls pumps, heaters and valves. The PLC communicates with temperature monitors through Ethernet. HMI of PLC and EPICS controls and monitors pumps, heaters, valves and temperature sensors through switching hub. The PLC HMI is developed and EPICS is also developed. The CSS of EPICS consists of control, monitor, parameter set-up, alarm and data browser screen. | |||

| THPMW012 | The Fast Interlock Controller for High Power Pulse Modulator at PAL-XFEL | controls, interlocks, operation, vacuum | 3561 |
|
|||
|
Funding: This work is supported by Ministry of Science, ICT(Information/Communication Technology) and Future Planning. The modulator control system for PAL-XFEL consists of a PLC unit (Programmable Logic Controller) and FPSCM (Fast Pulse Signal Conditioning Module). There are two kinds of interlock, which are dynamic and static interlocks categorized as analogue monitor and control signals, digital monitor and control signals. In case of dynamic interlocks, the internal interface of the PLC unit had to be modified due to operating within 10 ms time response from the interlock event. The fast pulse signal conditioning module is adopted for preconditioning the fast pulse and DC signals that inherently have high noise levels generated from a beam voltage, a beam current and EOLC current. Those EM (Electro-Magnetic) noises are generated by thyratron switching. The amplitude of the thyratron noise is large which causes the problem at the control devices, frequently. In this paper, the test results of the interlock control system will be described. |

| THPOW060 | Basic Design of Control System for IPM Linear Accelerator | controls, EPICS, linac, electron | 4082 |
|
|||
| A control system has been designed for the commissioning of 10 MeV linear accelerator which is under construction in institute for research in fundamental science (IPM). The IPM e-Linac is a traveling wave accelerator consisting of 62 components in five major sections: control and safety, beam injection, radio frequency production and transmission, acceleration tube and target. The existence of a central control system for controlling and monitoring all parts of the machine is necessary. The aim of the system design is to implement a fast and reliable control system which is easy to operate and extensible for future upgrades and improvements. For this purpose, EPICS has been chosen as the main environment due to high performance and distributed structure. In this system, Siemens PLC is used as EPICS IOC and graphical designs will performed by CSS and WinCC. In this study, first we present a brief description of the IPM electron linear accelerator, and then architecture of the control system will be discussed. | |||

| THPOY030 | Dependability Studies for CERN PS Booster RF System Upgrade | electronics, interlocks, booster, operation | 4159 |
|
|||
| Radio frequency systems are a vital part of almost all accelerators. The request for a higher beam bright-ness from the injector chain of CERN's Large Hardon Collider, as demanded by the future High-Luminosity program, has motivated, among many other upgrades, the construction of new RF equipment in the PS Boost-er. Because availability and reliability have an im-portant impact on the luminosity production in a col-lider environment, dependability studies have been performed on the new design of the RF system assum-ing different maintenance strategies. This paper will present the model, made with the commercial software Isograph, for dependability studies. In addition, a comparative study will be presented between the re-sults obtained from Isograph and from an analytical analysis. | |||

| THPOY042 | Evolution and Perspectives of Second Generation Magnet Interlock Systems at CERN | operation, interlocks, radiation, dipole | 4192 |
|
|||
| The CERN accelerator complex relies on thousands of superconducting and normal conducting magnets to guide the particle beams on their trajectories throughout the accelerator chain. In order to protect magnet and powering equipment from damage, complex magnet interlock systems are deployed and operated in the LHC and its injectors. Despite a very good track record during the first 10 years of operation, important consolidation activities are ongoing and planned to further increase the dependability of the injector chain and enhance the sys-tem functionality where required. This paper reviews the performance of the various magnet interlock systems at CERN during the past years of operation and presents the ongoing renovation projects carried out in the LHC in-jector complex to achieve the high level of dependability and maintainability required for long term operation. Finally, some design aspects of the existing LHC magnet interlocks will be discussed and possibilities to further enhance the dependability and functionality of the mag-net powering system will be presented in view of the High Luminosity LHC. | |||
