Boeing Radiation Effects Laboratory

Type of Simulator	Cf-252 fission source and Am-241 alpha source
Application	Single event effects
Test Object Size	About 20cm diameter, with about 2cm diameter exposure area
General Description	The BREL SEE test system is a Spectrum Sciences model 5005-TF test chamber. It uses either Cf-252 or Am-241 sources and has been modified for improved input-output capability. Devices are placed in a vacuum chamber and exposed to fission fragments and alpha particles to simulate the heavy ion cosmic ray environment found in space.
