	The TPS booster is a synchrotron with injection energy at 150 MeV and extraction energy at 3 GeV in 3 Hz. Booster main power supplies consist of one dipole power supply with maximum current 1200 Ampere and four quadrupole family power supplies with maximum current of 120/150 Ampere. The small power supply for booster corrector and sextupole is a low noise switching power supply with ± 10 Ampere current range. The TPS booster control environment is based on EPICS framework to support rich functionalities including power supply control, waveform management, operation supports, and so on. All power supplies support DC mode and 3 Hz ramping mode operation for TPS booster commissioning and operation. Efforts on control interface and functionality for TPS booster power supply will be summarizes.

	Taiwan Photon Source (TPS) is a third generation 3 GeV synchrotron light facility. The synchrotron radiation from a dipole can be used to observe the beam parameters. The synchrotron radiation monitor (SRM) systems were designed and implemented for the booster synchrotron and storage ring. The SRM for the booster synchrotron can serve to diagnose the energy ramping process. The beam size decreases when the energy increases was observed. In the storage ring, the streak camera was preferred to observe the beam behaviour of the consecutive bunches. The bunch length and longitudinal instability were observed. The preliminary beam test results are summarized in this report.

MOPTY075	Vibration Measurement of the Magnets in the Storage Ring of TPS	1112
	C.H. Huang, Y.-S. Cheng, P.C. Chiu, K.T. Hsu, D. Lee, C.Y. Liao NSRRC, Hsinchu, Taiwan
	Taiwan photon source is a 3rd generation synchrotron light source which is in beam commissioning at NSRRC. Orbit stability within 100 nm range is essential for such a small emittance light source. Technical noise from the vacuum pumps, water flow, etc. will cause the vibration of quadrupoles and deleterious orbit stability. In order to investigate the magnitude of vibration in the magnets of the storage ring, the vibration spectra of the lattice quadruples; the coherence between the magnets, girders and ground will be systematic investigated in this report.

	The TLS (Taiwan Light Source) is a third generation of synchrotron light source, and it has been operated since 1993. The TLS control system is a proprietary design. It was performed minor upgrade several times to avoid obsolete of some system components and keep up-to-date during last two decades. The control system of the TPS project (Taiwan Photon Source) is based upon the EPICS framework. To save resources for TLS control system maintenance, adopt EPICS for newly developed and rejuvenated subsystems for some of the TLS control interfaces includes BPM system, insertion devices, bunch-by-bunch feedbacks, electronics instruments interface and so on. Some EPICS related applications have been developed, and EPICS graphical user interface is also operated at the TLS control consoles environment normally. Current system allowed two kinds of control environments working together. The efforts will be described at this report.

The EPICS embedded programmable logic controller (PLC) was applied to control pulse magnet power supply.

The control information (status of the power supply, ON, OFF, warn up, reset, reading/setting voltage, etc.) can be accessed remotely using EPICS client tools. The TPS timing system provide trigger signals for pulse magnet power supplies. The Ethernet-based oscilloscope is employed to observe current waveform of pulse magnet power supply with EPICS support.
