F. Nava et al., ELECTRIC-FIELD AND PLASMA EFFECTS ON PROTON-IRRADIATED GAAS DETECTOR PERFORMANCE, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 410(1), 1998, pp. 68-73
The effect of the bulk damage on the detector performance was determin
ed as a function of the non-ionising energy loss of high-energy proton
s in semi-insulating GaAs. The study was performed by measuring the ch
arge collection efficiency of gamma-rays, protons, beta- and alpha-par
ticles on 24GeV/c proton irradiated detectors fabricated on Liquid Enc
apsulated Czochralski grown GaAs. The results obtained let us explain
the effect of the electric field strength and the plasma on the collec
tion of the charge carriers. (C) 1998 Elsevier Science B.V. All rights
