  The timing system of the Taiwan Photon Source is used to distribute trigger signals and synchronously clocks to all the equipment of the machine which need them. The timing system basically works by sending event codes from one event generator (EVG) through tree structured, bidirectional optical fiber network to many event receivers. To accommodate various operation and injection scenarios of the TPS storage ring and booster synchrotron and LINAC, timing sequencer design and control is crucial. The sequencer (event code) is stored at sequence RAM of the EVG module. In order to manage sequence RAM of EVG, the timing sequence control is considered to use Matlab scripts embedded in the timing master EPICS IOC. The timing sequencer design will be summarized in this paper.

  The TLS (Taiwan Light Source) is a third generation of synchrotron light source, and it has been operated since 1993. The TLS control system was developed and implemented by ourselves. The control system of our new project (TPS, Taiwan Photon Source) is developed and based upon the EPICS framework. To earn more experiences on the EPICS usage, some of the TLS newly installed subsystem run EPICS directly. For example, BPM system, bunch-by-bunch feedback system, remote oscilloscope waveform access and so on adapt the EPICS interface to control and monitor. The EDM and Matlab (with LabCA) toolkits are used as EPICS graphical user interface, and it is also operated at the TLS control consoles environment normally. The archive system transaction between the TLS control system format and EPICS PVs (Process Variables) has been implemented for user access with the existing archive viewer. The efforts will be described at this report.
