Abstract

The design of the vacuum system at the 3 GeV Taiwan Photon Source (TPS) is described. A localized pumping configuration of the bending chambers (B‐chamber) and the injection section of the storage ring is adopted to confine and evacuate the photon‐stimulated desorption from the absorbers induced by synchrotron light. The photon absorbers are carefully designed to reduce the photoelectron yield and to protect the downstream components. Non‐evaporable getter (NEG) strips are installed inside the insertion device chambers (ID‐chamber) to increase the linear pumping speed to solve the conductance‐limit problem. Monte Carlo and iterative simulation programs are utilized to calculate the pressure profiles in both the bending section and the straight section to optimize the location of the vacuum pumps. The simulation results show that the pressure satisfies the requirement (< 1 × 10−9 torr) for a 10‐hour beam lifetime at 3 GeV, 400 mA after a conditioning time of 100 Ah.
