Development of Spectroscopy Instrumentation based on SDD and CZT Detectors.
Beta decays have significantly enhanced the understanding of nuclear physics, weak interactions, and neutrinos. In recent years, there has been a renewed interest in these topics, and a promising new approach involving the adoption of Silicon Drift Detectors (SDD) has emerged. In this context, a dual-channel SDD-based spectrometer has been designed to study allowed and forbidden beta decays across a wide energy range (spanning from 10 keV to 1 MeV).
Another project I am involved in focuses on designing an ASIC for reading out Cadmium Zinc Telluride (CZT) detectors. These detectors feature several key properties, including the ability to operate at ambient temperature, high density, high absorption coefficient, high count rate, excellent energy resolution, and the capability to convert high-energy photons into electron-hole pairs directly. The ASIC will be fabricated using a 0.18 µm process and is part of a European project, whose aim is to include Artificial Neural Network in radiation detection to improve the accuracy and speed of measurements while reducing digital data output.
