Description
Abstract: Single sided silicon strip detectors (SSD) and double sided silicon strip detectors (DSSD) are silicon based micro-strip detectors that are widely used in various physics experiments and medical applications.
These detectors are currently commercially available with thicknesses and pitch sizes up to 2000 μm each, however most of the ones being used in experiments are rather thin detectors (less than 1000 μm in thickness and pitch size). Currently we are testing thick detectors for their potential to be used to create a future Compton telescope which will operate in the MeV region.
This telescope would require DSSDs thicker than what is widely used.
Using Silvaco's TCAD software package, a model was developed to simulate the properties and performance of these detectors in terms of depletion voltage, capacitance, leakage current, charge collection efficiency and charge sharing. The model was bench-marked by comparing its simulation output with measurements made on several detectors, and then the simulation was extended to thicker detectors where only a few experimental data exists.
