At the Paul Scherrer Institute (PSI), we are developing inverse Low-Gain Avalanche Diode (iLGAD) sensors with a thin entrance window (TEW) in collaboration with Fondazione Bruno Kessler (FBK). The TEW design is used to enhance the charge-collection efficiency near the sensor surface. In our latest batch, the quantum efficiency (QE) exceeds 85% at 250 eV, which is comparable to state-of-the-art...
We present the performance of two X/Gamma-ray detection systems based on Low-Gain Avalanche Diodes (LGADs) with a wide range of multiplication gains: the first LGAD is characterized by a very-low gain range (M_s=1.2-1.9), while the second one by a high-gain range (M_s=10.2-19.3). To allow the evaluation of the ultimate energy-resolution limits of the LGAD sensors, the read-out is performed...
The development of hybrid pixel detectors combining the JUNGFRAU charge-integrating ASIC with inverse Low-Gain Avalanche Diode (iLGAD) sensors continues to advance toward high-performance soft X-ray Resonant Inelastic X-ray Scattering (RIXS) experiments. The project aims to achieve both high frame rates (2 kHz continuous and up to 250 kHz in burst mode with the most recent ASIC version...
n-type Low Gain Avalanche Detectors (nLGADs) have already demonstrated excellent performance for shallow-penetrating radiation detection, including low-energy photons down to the deep-ultraviolet (DUV) spectrum, as well as low-energy protons and ions. They are specifically designed to achieve high gain only when radiation penetrates the near-surface region (approximately 1–2 µm). We report on...
