  The Hefei Light Source II (HLS-II) is a vacuum ultravi-olet (VUV) synchrotron light source. A major upgrade of the light source was finished in 2014, and the timing system was rebuilt with event-system to meet synchroni-zation requirements of the machine. The new timing system provides about 100 output signals with various interfaces. The time resolution of this system is 9.8 ns for most devices and 9 ps for the electron gun and the injec-tion kickers. The measured jitter of the output signal is less than 27 ps (RMS). In order to improve the perfor-mance of light source, the top-off operation mode has been planned. As part of this plan, both the hardware and the software of the timing system are upgraded. By ob-taining real-time data of beam measurement of storage ring, the automatic selection of the bucket is implement-ed. With any designated bunch pattern, top-off injection is achieved, and the storage ring beam can be uniform filled well.

  The Taiwan Photon Source (TPS) is a 3-GeV third-generation synchrotron light source located in Hsinchu, Taiwan. The post-mortem (PM) system is act as an important tool to diagnostic the cause of trip events caused by beam loss. A MATLAB-based and web-based viewer were developed to plot and view the each event to understand the cause and effect of the event. The post-mortem viewer architecture and implementation were presented in this report.

THCPA07 Development of an Expert System for the High Intensity Neutrino Beam Facility at J-PARC ion, septum, experiment, proton 1229

  A high intensity neutrino beam produced at J-PARC is utilized by the T2K long baseline neutrino oscillation experiment. To generate the high intensity neutrino beam, a high intensity proton beam is extracted from the 30 GeV Main Ring synchrotron to the neutrino primary beamline. In the beamline, one mistaken shot can potentially do serious damage to beamline equipment. To avoid such a consequence, many beamline equipment interlocks which automatically stop the beam operation are implemented. If an interlock is activated, the beam operator references the operation manual, confirms the safety of the beamline equipment and resumes the beam operation. In order to improve the present system, we are developing an expert system for prompt and efficient understanding of the status of the beamline to quickly resume the beam operation. When an interlock is activated, the expert system references previous interlock patterns and infers what happened in the beamline. And the expert system will suggest how to resume the beam operation to the beam operator. We have developed and evaluated this expert system. In this talk, we will report the development status and initial results.

THPHA145 Integration of PLC and PXI Control Systems ion, controls, PLC, hardware 1725

  Engineers are often challenged with the need to integrate several technologies to find optimal solutions when designing new control architectures. Generally, the technical solutions chosen require the combination of various industrial products such as PXI systems for applications requiring fast acquisition, analysis and reaction times, while PLCs are commonly used for their reliability and their ability to withstand industrial environments. The needs to exchange information between these different technologies can today be solved by using industrial fieldbuses such as Profibus DP or Profinet IO. This paper describes the technical aspects of the two options, focussing on their advantages and constraints. The experience gained with integrating PXI and PLC systems as part of the 2016 consolidation project of the control of the kicker systems of the Antiproton Decelerator (AD) at CERN will be presented.
