Abstract
Taiwan Photon Source (TPS) is under construction at the National Synchrotron Radiation Research Center (NSRRC). This 518 m circumference synchrotron accelerator will generate 3 GeV and 500 mA high-energy X-rays. Absorbers in the storage ring will receive relatively high power densities (at a distance of 2.2 m from the dipole source). Three types of crotch absorbers for B1–B3 storage chambers were designed and prototyped. An end absorber in B3 is also designed and implemented to protect the downstream components in the chamber from being heated by the synchrotron radiation. Intensive vacuum brazing between Oxygen Free High Conductivity copper (OFHC) and stainless steel was carried out while fabricating the absorber assembly. The analysis, design and construction of several absorbers are reported in this paper.
