The CASS thermal/vacuum facility is a vacuum chamber (4 ft diameter x 7 ft long) with porting for cold gas/LN2 interface to custom thermal shrouds with heaters for thermal control in the -150C to +50C range. Vacuum pressures of 10-6 Torr are achievable through the diffusion pump and cold trap. Automated control of the thermal system and cold trap nitrogen supply allows users to operate the system around the clock for cost effective thermal/vacuum environmental testing of space instrumentation.
CASS engineers and programmers have decades of experience in instrument and system design for radiation detection and space applications. They have developed lung function instrumentation for the astronauts on the Space Shuttle, high resolution electron detectors for electron microscopy at the National Center for Microscopy and Imaging Research, as well as packaging phototubes for use in hostile environments deep undersea or in outer space.
