Description
14.5K cryogenic Helium is the refrigerating medium of the Cold Neutron Source (CNS) Facility. Hydrogen 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 subsystems is the base for obtaining cold neutron. And RCS debugging is the most complex one in all works. Trouble and problem solving during the commissioning operation of RCS is the primary coverage of this paper. (authors)
