Readout responses of inclined strips in position sensitive detectors

Abstract

A study about readout responses for the inclined strips in position sensitive detectors has been done using theoretical predictions and experimental results. Inclined strips are almost along the displacement direction of incident particles. Rotating conventional strips to near horizontal strips decreases the number of strips by a tangential factor for long length position sensing. In addition to the channel reduction, the inclined strips modify about ten percent (10%) in the readout linearity in comparison to the long length zigzag patterns. There is resolution degradation because of the inherent high sensitivity of these strips to the avalanche size (about 8% of the detector full length). Double peak responses were observed for sensing the positions of the incident particles. Our theoretical predictions and experimental results are discussed.
