Device simulations of the silicon microstrip detectors that will equip the Tracking System of the GLAST experiment have been performed. The influence on the electric characteristics of both strip pitch and width have been evaluated. First, a DC calculation is done to predict the risk of breakdown within the working bias conditions. Then, the backplane and(More)
We present the first results of timing and energy resolution of two newly developed tiles based on FBK RGB-HD SiPMs. The first tile has dimensions of 32×32 mm 2 and is composed of 8×8 SiPMs, with a regular pitch of 4 mm and a cell size of 25×25 μm 2. Although manufactured with a standard bond wire technology, the tile achieves a fill factor at the tile(More)
Silicon Photomultipliers (SiPM) are arrays of many (thousands or tens of thousands) Single-Photon Avalanche Diodes (SPADs), with integrated passive-quench per each pixel. Like SPAD, each SiPM cell works in Geiger mode and the output current is the sum of all the cells, giving a signal proportional to the number of photons detected. They are compact and(More)
We present the characterization of a novel Position-Sensitive Silicon Photomultiplier, called Linearly-Graded SiPM (LG-SiPM). The position encoding is obtained through a charge sharing approach, implemented by means of a current divider, directly integrated on die. We fabricated prototypes of the 2D LG-SiPM with two different dimensions, with an active area(More)
A new multi-modality imaging tool is under development in the framework of the INSERT (Integrated SPECT/MRI for Enhanced Stratification in Radio-chemo Therapy) project, supported by the European Community. The final goal is to develop a custom SPECT apparatus that can be used as an insert for commercially available MRI systems. INSERT is expected to offer(More)
