Integrate test and qualify NASA facility class payloads on the ISS JEM-EF
This paper describes the processes that the Low Temperature Microgravity PhysicsFacility (LTMPF) follows or will follow to meet the qualification requirements imposed by the Jet Propulsion Laboratory (JPL), by the Microgravity Research Program Office (MRPO) at MSFC, by the ISS Payloads Office (OZ) at JSC, and by NASDA's JEM Element Integration Office.

Test results and in-orbit operation of the Infrared Astronomical Satellite circumvention circuit
The IRAS circumvention circuit (CC) eliminates the unwanted charged-particle pulses from the IR signal. The operation of the CC along with preflight and in-orbit testing is described. Ground testing of the brassboard circuit using a simulated preamplifier output showed that the CC would perform the circumvention function as designed. When all flight detectors and preamplifiers became available, the CC was tested using a gamma source to simulate charged-particle sources; with the low energy deposited in the detectors (20 keV average) the noise was reduced by up to 5 times with the CC turned on. In-orbit results show that the CC decreases the unwanted charged-particle background noise by up to two orders of magnitude. The difference in the results with the CC on and off is so great that the science team has recommended that no data be taken with the CC off.
