Two modules of the L3 Silicon Microvertex Detector (SMD) have been tested on beam. The active area of the modules consists of double sided silicon microstrip detectors; the implantation pitch is 25 mum and 50 mum in the junction and ohmic side, respectively. The detectors are read out by a VLSI radiation hard amplifier (SVX-H). The position resolution, with a readout pitch of 50 mum and 200 mum for the two sides, is determined to be 7.0 mum and 14.3 mum. A signal to noise ratio greater-than-or-equal-to 16 and a detection efficiency greater-than-or-equal-to 99% are measured for both sides.

Abstract
Two modules of the L3 Silicon Microvertex Detector (SMD) have been tested on beam. The active area of the modules consists of double sided silicon microstrip detectors; the implantation pitch is 25 mum and 50 mum in the junction and ohmic side, respectively. The detectors are read out by a VLSI radiation hard amplifier (SVX-H). The position resolution, with a readout pitch of 50 mum and 200 mum for the two sides, is determined to be 7.0 mum and 14.3 mum. A signal to noise ratio greater-than-or-equal-to 16 and a detection efficiency greater-than-or-equal-to 99% are measured for both sides.File in questo prodotto:
