Abstract

Operating at 8 GeV with 1 amp of beam current, the CESR B-factory produces highly intense synchrotron radiation (SR). In response to other vacuum chamber design concerns, a discrete bar absorber has been designed to receive the x rays in the transition region. The absorber is an actively cooled copper extrusion. Finite element analysis has been used to predict the thermal and structural response of the absorber. Elastic/plastic stress analyses predicted localized plastic deformation and since operation is cyclic, fatigue failure has been considered. Preliminary testing using a rastered electron beam for both steady state and fatigue testing has begun.
