Abstract

We describe an array of 16 planes of mustrip silicon detectors used in the SPS-WA75 experiment. Its aim was to give predictions on the localization of interactions of 350 GeV/c particles in a thick emulsion target, together with a 3-dimensional reconstruction of the secondary tracks. It is shown that the detector array contributes to the vertex location errors by ± 20 μm and ± 500 μm transverse to and along the beam direction, respectively. Mechanical layout and electronics are presented. All strips are analogically read out, using a pulse stretching method which allows a serial-parallel multiplexing of 32 channels, and therefore lowers the electronics cost. Operation and detector performance are described with a study of clustered events.
