Abstract

In this work is reported a study on the response of double sided silicon strip detectors. In order to investigate the effect of the electrode segmentation on the detector response, two experiments were performed aimed to measure the efficiency for full energy detection. Results show that the efficiency for full energy detection, that is directly related to effective width of the inter-strip region, varies with both detected ion energy and bias voltage. The experimental results are qualitatively reproduced by a simplified model based on the Shockley-Ramo-Gunn framework.

Highlights

  • Double Sided Silicon Strip Detectors (DSSSDs) are widely used in high energy and in nuclear physics studies

  • In particular phenomena such as charge sharing and opposite polarity signals can occur. Such phenomena make the efficiency for full energy detection for DSSSDs lower than 100% as one can expect from a single pad detector

  • A first measurement was performed by mean of 7Li and 16O beams at different energies, showing that the efficiency for full energy detection depends on the energy and type of the detected ion and on the applied bias voltage
