摘要：

The performance of a silicon detector with two-dimensional pad readout, intended to be used in the trigger of experiment HELIOS (NA34), has been investigated in a proton/pion beam of 200 GeV/c momentum at the CERN SPS. The data can be described by the convolution of the Landau distribution with a Gaussian, taking into account long distance collisions and electronics noise. Uniformity in peak loss was found to be better than 7%. The response for single tracks through the detector is characterized by the total number of pads with a threshold value (multiplicity), and the number of adjacent pads, responding to a single particle (cluster size). Data on multiplicity and cluster size as a function of threshold will be discussed. Detection efficiency for particles has been measured over the pad area and across the pad boundaries.
