Ja. Lauber et al., ENERGY-DEPENDENCE OF DAMAGE TO SI PIN DIODES EXPOSED TO BETA-RADIATION, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 396(1-2), 1997, pp. 165-171
The radiation damage to Si PIN diodes such as used in the OPAL SiW lum
inometer was studied. It was found that the increase in leakage curren
t after exposure to bursts of 500 MeV electrons is >0.2 x 10(3) times
higher than after the exposure of an equivalent dose of electrons emit
ted from a Strontium beta source. Highly-energetic electrons produce a
similar amount of damage to silicon as do protons or neutrons.
