Mm. Angarano et al., BEAM TEST-RESULTS FOR SINGLE-SIDED AND DOUBLE-SIDED IRRADIATED SILICON DETECTOR PROTOTYPES OF THE CMS CENTRAL DETECTOR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 409(1-3), 1998, pp. 135-138
We present the results of two beam tests performed in July and Septemb
er 1996 at CERN in order to study the behaviour of irradiated single-
and double-sided silicon detectors from different manufacturers. All d
etectors had been irradiated with neutrons, up to a maximum fluence of
3.6 x 10(13) cm(-2), and had reached type inversion. Signal-to-noise
ratio, resolution and efficiency have been studied for different value
s of detectors bias voltage, operation temperature (ranging from - 10
degrees C to f 20 degrees C) and read-out pitch and, in some case, for
different incidence angle of the incoming particle. The results are p
romising, since no dramatic deterioration of detector performances has
been observed. (C) 1998 Elsevier Science B.V. All rights reserved.
