Issue Date: | 2019 | Volume: | 2019 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC) | Series: | IEEE CONFERENCE RECORD - NUCLEAR SCIENCE SYMPOSIUM & MEDICAL IMAGING CONFERENCE | First Page: | 1 | Abstract: | We report on the development and of a complete X/γ rays detection system (10-1000 keV) based on CZT spectrometers with spatial resolution in three dimensions (3D) and a digital electronics acquisition chain. The prototype is made by packing four linear modules, each composed of one 3D CZT sensors. Each sensors is realized using a single spectroscopic graded CZT crystal of about 20×20×5 mm3. An electrode structure consisting of 12 collecting anodes with a pitch of 1.6 mm and 3 drift strips between each pair of anodes for 48 strips (0.15 mm wide) on the anodic side was adopted. The cathode is made of 10 strips with a pitch of 2 mm and orthogonal to anode side strips. Since the reading of the drift strips will carried out by putting in parallel all the strips that occupy the same place with respect to a collecting anode, the channels number for each sensors is only 25. The detector readout front-is based on custom designed low noise charge sensitive pre-amplifiers (CSP) implemented in hybrid 16 channels board. The CZT module and its CSP front-end provide the signals to a multichannel Digital Pulse Processing FPGA based system able to digitize and process continuously the signals. The digital system implement an innovative firmware that allow performing fine time-tagging, online pulse shape and height analysis with good energy resolution. | Conference Name: | 2019 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC) | Conference Place: | Manchester, UK | Conference Date: | 26 October-2 November, 2019 | URI: | http://hdl.handle.net/20.500.12386/30127 | URL: | https://ieeexplore.ieee.org/document/9059948 | ISSN: | 1082-3654 | ISBN: | 978-1-7281-4164-0 | DOI: | 10.1109/NSS/MIC42101.2019.9059948 | Fulltext: | open |
