20. Optimizing Anode-Only Readout for High-Resolution Coded-Aperture Gamma Imaging with Pixelated CdZnTe Detectors

Guillaume Montémont (CEA-LETI)

Simultaneous measurement of interaction position and energy is essential for semiconductor gamma imagers, but optimizing detection efficiency, energy resolution, and spatial resolution presents a significant challenge due to competing trade-offs among noise, signal induction, and readout electronics. While techniques such as cathode readout, pulse shape analysis, and multi-anode readout have...

10. Direct Digitization of Transistor-Reset Preamplifier Outputs Using an Interleaved 20-bit SAR ADC Architecture for High-Rate X-ray Spectroscopy

We present a novel digital acquisition and processing architecture for high-count-rate X-ray spectroscopy based on the direct digitization of transistor-reset preamplifier outputs. The proposed approach overcomes the limitations of conventional analog reshaping techniques, which suffer from baseline distortions and pile-up effects at high event rates, by employing a high-resolution 20-bit...

23. Integrated Front-End Electronics and Flexible Interconnection Systems for Segmented High-Purity Germanium Detectors

Giacomo Secci (INFN Milano)

Segmented high-purity germanium (HPGe) detectors are essential tools in advanced gamma spectroscopy. However, many of their technical and manufacturing details remain proprietary to industry. To overcome this limitation, the Italian Institute for Nuclear Physics funded the N3G Project, aimed at developing new segmented HPGe detectors while building in-house expertise for their design,...
