Abstract

Results are presented of the first liquid helium temperature testing of the Space Infrared Telescope Facility (SIRTF) prototype Secondary Mirror Assembly (PSMA). Attention is given to the key requirements of PSMA, its design, and the test instrumentation and procedures. Results of preliminary tests completed to date showed that the design of the PSMA forms a very strong basis for meeting the SIRTF requirements.
