Hybrid Absorber for the RFOFO Ring Cooler V. Balbekov, FNAL, June 30, 2003 Abstract A special absorber for the RFOFO ring cooler is proposed. It presents a flat cryogenic vessel with liquid hydrogen and inserted lithium hydride wedge. Its advantages over a liquid hydrogen wedge absorber are a simpler design and thiner aluminum windows. Cooling simulation shows that the RFOFO cooler with this absorber has higher performances.
