Parts are irradiated while performing their functions, and the laser pulse can be time controlled to investigate the effects of radiation as a function of timing within the clock cycle. Susceptibility to single-event phenomena can be evaluated, and improved risk assessments can be made. This facility works in close collaboration with the Single Event Upset Testing Facility. This facility is used to determine the vulnerability of spacecraft electronic components to upset, latchup and burnout as a result of exposure to the energetic particle environment, especially heavy ions, found in space. The facility consists of a large vacuum enclosure, motion table, and computer systems that allow monitoring and recording of the performance of complex electronic devices under bombardment by energetic heavy ions from protons to ions heavier than iron.
Many programs require digital signal processors in their space systems.
There are, however, no radiation-hardened digital signal processors currently available. This situation forces programs to consider the use of COTS processors. The Aerospace Corporation. All rights reserved. Last modified on November 26, 1999.
