Silicon Drift Detectors (SDD) equip the two intermediate layers of the Inner Tracking System (ITS) of the ALICE experiment. The SDD is required to provide a spatial precision of about 35 µm along the drift direction and 25 µm along the anode axis. In these detectors, the drift velocity depends on temperature (v α T−2.4), giving a 0.8%/K variation at room temperature. To achieve the required resolution...
In this paper a novel, Readout Module (RM) for Single Photon Detector (SiPD has been described. The electronics design is based on the concept of virtual instrumentation RM consists of SiPD preamplifier, shaping amplifier, discriminator, multi channel analyzer and control module connected to a PC through the USB bus and of PC application software. The RM can be used for investigation of different...
