Abstract :
A high heat load crotch absorber has been designed for the Advanced Photon Source (APS) storage ring curved chambers. The absorber, which uses a beryllium diffuser brazed to oxygen free high-conductivity copper (OFHC) plates, has been optimized to spread the beam power in order to reduce its temperature rise and thermal stresses. Circular copper tubes are brazed to the absorber for water cooling. The absorber design and analytical results from a three-dimensional finite element model are presented in this paper
