The Project Technology  branch, code PMF (formerly Sensors and Instrumentation, code 
SFT) has been involved in the testing and development  of infrared detector arrays for 
space-based observation systems for several decades.  These include detectors for IRAS, 
Spitzer (formerly SIRTF), Gravity Probe-B (visible detectors ),  and for upcoming 
missions such as JWST (formerly NGST).  In the  case of Spitzer, the flight detectors for 
IRAC (SBRC CRC-744) were tested in our lab, as well as detectors from the lot for IRS 
(Rockwell 128^2) and representative CRC-696   multiplexers from the MIPS instrument 
lot.  For JWST we have tested megapixel near and mid infrared arrays for NIRCam, 
NIRSpec and MIRI.  Additionally, we develop far IR detectors (Ge and GaAs) and have 
been successful in our two ROSS proposals for projects involving development of 
detectors and multiplexers.  In the years since 1989 we have performed quite a number of 
cyclotron irradiation runs  for radiation testing of many candidate parts for space 
applications, including multiplexers, hybrid sensor chip assemblies, and materials for 
structures and supports of detector assemblies.  Examples from several of these areas will 
be shown and discussed.
