The high resolution silicon telescope of the INSULAB group

This thesis has focused on the study of the performance of the high resolution tracking system (telescope) of the INSULAB group and on the implementation of a new data acquisition (DAQ) to comply with the high rate of the CERN North Area extracted beams. This system has allowed to increase the DAQ rate by a factor two with respect to the "standard" electronics. The INSULAB telescope is designed to test detectors ranging from calorimeters to more complex systems like in the case of the bent crystals studied by the COHERENT experiment. The telescope consists of four 300 $mu$m thick double side silicon strip detector modules with an area of 1.92$ imes$1.92 cm$^{2}$ and 384 strips. The readout pitch is 50 $mu$m on both sides of the module but the junction side has an implant pitch of 25 $mu$m (and thus a floating strip) to improve the resolution. The telescope has been installed on the H4 beamline at the CERN SPS for the commissioning of the new readout system in June 2012. The results are analyzed in terms of the overall noise, the identification of the cluster (the group of strips in which the particle has released its energy) and the signal to noise ratio. A detailed study of the spatial resolution and the distribution of the charge produced by the particle among the strips, which can be reconstructed with the $eta$ algorithm, is also presented.
