Abstract

The performance of a telescope of Micro-Strip Gas Chambers (MSGC) has been studied in a beam of minimum ionizing particles. Detectors of two different pitches have been studied. The position resolutions is obtained by reading out the cathodes and interpolating based on the amplitude of the signals. The position of the hit in the chamber is found to differ systematically from the cluster centroid position. A correction method is derived from the data and applied to improve the resolution. After correction, the spatial resolution of chambers with 200 μm pitch is found to be 42 μm, and for the 400 μm pitch detectors the resolution is 42 μm. The improved interpolation for the 400 μm pitch chamber can be understood in terms of the better signal to noise observed for the 400 μm pitch detectors. The degradation in resolution as a function of angle of track incidence is also expected to be less for the larger pitch chambers
