演讲内容摘要：

Liquid helium (LHe) cryocondensation pump is an ideal vacuum pumping device for maintaining a specified pressure distribution inside the neutral beam injector system (NBIS). Its structure is different from that of cryocondensation pump used in industry or small laboratory. In order to optimize its cryopumping performance,parameters necessary for evaluating the pumping performance was analyzed. Measurements to optimize them were obtained. One prototype cryocondensation pump mounted in the drift tube of NBIS was designed and manufactured. Pumping performance test for pumping speed,pumping capacity was done. The results indicate that a LHe cryocondensation pump with designed cryopanel structure could meet the requirement of NBIS for vacuum system very well. The results may apply to the cryopanel cooled by forced flow LHe.

第22届国际制冷大会于2007年8月21日在北京国际会议中心隆重召开，会议为来自世界各地的科学家和工程师提供一个互相交流和分享各自成功经验的机会，以使制冷技术在今后几十年保持持续快速的发展。
