摘　　要：本文详细介绍了放置在100 MeV强流紧凑型回旋加速器主磁铁谷区的实验低温冷板抽气装置的设计,并加工了实验低温冷板性能测试罩,对实验低温冷板内置及外置情况下的抽气参数如抽速、极限压力、抽气容量等参数进行了测试,并对两种不同情况下的测试结果进行了分析比较。结果表明,内置抽速为外置抽速的2.67倍,外置极限真空为内置极限真空的2.75倍,结合100 MeV强流紧凑型回旋加速器的实际情况,100 MeV低温板系统的理论抽速与入口综合流导之比应满足1.1倍工程设计要求。This article detailed introduces the design and test of cryopanel pumping system placed in magnet valley of 100 MeV high intensity compact cyclotron in CIAE. Parameters of cryopanel pumping system such as pumping speed, ultimate pressure, gas capacity were tested, and the test results of two different cases were analyzed. The results show that the plug-in pumping speed is 2.67 times of the external type, and the ultimate pressure of external type is 2.75 times of plug-in type. According to the ac- tual demand of 100 MeV high intensity compact cyclotron, the pumping speed is 1.1 times of inlet conductance.
