R. Bates et al., MEASUREMENT OF HIGH-INTENSITY PROTON-BEAM PROFILE WITH A GAAS SIU SURFACE-BARRIER DETECTOR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 395(1), 1997, pp. 26-28
A GaAs detector made of semi-insulating, undoped (SIU) material was us
ed to measure the profile of the 24 GeV proton scanning beam which was
used for irradiation tests at the CERN PS, the measurement was perfor
med at the end of the test period after a fluence Phi approximate to 1
.5 x 10(15) cm(-2). The result is compared with a profile obtained wit
h colour centre densitometry in glass.
