The electronics will not degrade the resolution requirements up to a level of 10 neutrons, 's or charged particles per cm per RHIC year. The lifetime of the detector is set to be 10 years. The noise level has to be constant at any radiation level up to the level stated above.
This results from calculations performed independently by the RHIC group (Alan Stevens) and the Los Alamos radiation group (Laurie Waters).
CMOS and bipolar specifications include radiation requirement.
