May 1, 2022 · 2D-flood maps were obtained by placing a 137 Cs gamma ray source in the center of the filed-of-view (FOV) at a distance of 30 cm from the detector face from which one can discern the effects of applying various light guides.
Jun 20, 2023 · In this work, we use a neural network model trained on synthetic NaI(Tl) urban search data to compare some of these explanation methods and identify modifications that need to be applied to adapt the methods to gamma-ray spectral data.

- Left: An illustration showing the energy levels of the 4f and 5d electron configurations of Ce, the dopant responsible for the luminescence in lanthanum halide scintillators.
- A scale drawing of the OSO-3 gamma-ray instrument. The photomultipliers are labeled 1 through 15. A typical event in which an incident gamma-ray produces electron-positron pair in S is indicated schematically.
- The SPI instrument on-board the INTERnational Gamma-Ray Astrophysics Laboratory (INTEGRAL). The main detector core comprises 19 HPGe detectors with a hexagonal cross section that are heavily shielded on the sides and bottom by the BGO based detectors, as well as by a plastic scintillator above, providing active anticoincidence restriction for particles and gammas entering the instrument from directions outside of the FOV.
Gamma-ray detectors are devices that can achieve high spatial resolution for imaging gamma rays, improving the performance of gamma cameras by being compact and lightweight. They typically consist of pixelated arrays and photomultiplier modules, along with miniature electronics for data acquisition and processing.
