冷中子源装置利用14．5 K的低温氦气作为制冷剂。通过制冷系统的不停运转，将冷源氢系统内的氢液化。液态的氢充满着整个堆内部件系统的慢化剂室，使得其周围的热中子与液氢慢化剂进行能量交换，变为冷中子，再通过中子导管将冷中子输送到散射大厅各台谱仪上。冷源装置所有子系统调试运行的成功是获得冷中子的基础。在冷源调试中，氦制冷系统调试运行最为繁琐。着重介绍氦制冷系统在调试过程中遇到的问题及解决措施。

14.5K cryogenic Helium is the refrigerating medium of the Cold Neutron Source ( CNS) Facility.Hy-drogen is liquefied from normal atmospheric temperature by the operation of CNS Refrigeration Cryogenic System (RCS).Liquid hydrogen overflows the Moderator Chamber .Thermal neutrons around liquid hydrogen deliver their energy to liquid hydrogen and then they become cold neutrons .Cold neutrons travel along the neutron guide tube and then arrive to the neutron spectrometers in the scattering hall .Stably operating of all CNS sub-systems is the base for obtaining cold neutron .And RCS debugging is the most complex one in all works .Trou-ble and problem solving during the commissioning operation of RCS is the primary coverage of this paper .
