	The vacuum interlock and monitor systems of Taiwan Photon Source are designed to maintain the ultra-high vacuum condition and to protect the vacuum devices. The pressure readings of ionization gauges are taken as the judgment logic to control the opening and closing of sector gate valves so as to protect the ultra-high vacuum condition. Monitors of the water-cooling system and the chamber temperature serve to protect vacuum devices from radiation hazards. The preparation, installation and status of the interlock and monitor systems are presented in this paper.

	The booster of Taiwan Photon Source (TPS) is designed for 3GeV full energy injection ramped up from 150MeV. It is a synchrotron accelerator of 496.8m. The major vacuum system is elliptical tube made of 304 stainless steel. The inner cross section is 35*20 mm with 0.7 mm thickness. The elliptical tubes were chemical cleaned and ozonated water cleaned before installation. The bending tube was assembled and aligned into dipole magnet at laboratory. The BPM support and pumping chamber support was aligned with 0.3 mm deviation. The BPM chamber and pumping chamber was assembled firstly. The elliptical tube and bellows was installed to connect BPM, pumping chamber and bending chamber. The cold cathode gauge and TMP was mounted on pumping chamber. The pressure data and residual gas analysis will be described in the paper.

WEPME055	Residual Gas in the 14 m-long Aluminium Vacuum System of the Storage Ring of Taiwan Photon Source: toward Ultra-high Vacuum	2396

	In the Taiwan Photon Source project, the storage ring includes 24 sectors (each of length 14 m) of an aluminium vacuum chamber system. The design, manufacture, cleaning, welding and assembly of the vacuum components were undertaken by the NSRRC vacuum group. The ultimate objective is to attain a leak-tight, ultra-high vacuum and a vacuum system with a small rate of outgassing. In this work, we used a residual-gas analyzer (RGA) to analyze the variation of residual gas during proceeding toward ultra-high vacuum. This process, which led the pressure down to ~10^-11 torr, includes baking, operation of ion pumps, degassing of hot cathode gauges and activation of NEG pumps. When a sufficiently small low pressure is attained, the ion pumps are turned off to test the building up of pressure. The outgassing property and the variation of the residual gas of the aluminium chamber and the ion pumps can be measured.

The vacuum interlock and monitor systems of Taiwan Photon Source are designed to maintain the ultra-high vacuum condition and to protect the vacuum devices. The pressure readings of ionization gauges are taken as the judgment logic to control the opening and closing of sector gate valves so as to protect the ultra-high vacuum condition. Monitors of the water-cooling system and the chamber temperature serve to protect vacuum devices from radiation hazards. The preparation, installation and status of the interlock and monitor systems are presented in this paper.

In the Taiwan Photon Source project, the storage ring includes 24 sectors (each of length 14 m) of an aluminium vacuum chamber system.
