Abstract
This article summarizes the operational status of the closed-cycle refrigerators (CCRs) used to cool traveling-wave masers in the DSN. The improved CCRs have now replaced virtually all the old Model 210s. The reliability of the new system has lived up to all expectations, A continuing effort is made to simplify the system in order to further improve its reliability. The second part of this article describes a simple way of eliminating the oil pump which is used to cool and lubricate the compressor.
