A. Adam et al., TEST BEAM RESULTS FROM THE PROTOTYPE L3 SILICON MICROVERTEX DETECTOR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 344(3), 1994, pp. 521-528
We report test beam results on the overall system performance of two m
odules of the L3 Silicon Microvertex Detector exposed to a 50 GeV pion
beam. Each module consists of two AC coupled double-sided silicon str
ip detectors equipped with VLSI readout electronics. The associated da
ta acquisition system comprises an 8 bit FADC, an optical data transmi
ssion circuit, a specialized data reduction processor and a synchroniz
ation module. A spatial resolution of 7.5 mum and 14 mum for the two c
oordinates and a detection efficiency in excess of 99% are measured.
