Temperature oscillation characteristics of loop heat pipes (LHPs) for alpha magnetic spectrometer (AM S) cryocoolers during thermal vacuum and thermal balance (TVTB) testing were determined. Temperature oscillation only occurred for only one of eight LHPs. Temperature oscillations normally occurred at high sink temperature and/or heat load. Inclusion of a bypass valve was an effective measure to suppress temperature oscillations, because vapor at the condenser was not saturated when the bypass valve was open.
