AN EDGE-ON SILICON STRIP DETECTOR FOR X-RAY-IMAGING

A silicon strip detector for the SYRMEP (SYncrotron Radiation for MEdi cal Physics) experiment has been designed and realised. The main featu res of this detector are AC-coupling through integrated coupling capac itors, DC biasing by means of a gated punch-through structure, bulk co ntact on the junction side through a forward-biased p(+) implant and i ntegrated fan-in on active silicon. Results of laboratory tests of the detector parameters, allowing a thorough evaluation of the technologi cal solutions employed, are presented. The functionality of the detect ors and the charge collection linearity have been tested with differen t gamma sources, using hybrid, low-noise front-end electronics.
