It has become apparent that Silicon, though an excellent choice as a sensing material for current particle detectors, suffers greatly when exposed to heavy radiation, degrading properties like charge collection efficiency and increasing noise levels. Future collider experiments will require it to withstand stronger radiation fields. Therefore, either a frequent replacement of detectors, a leap...

The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) will increase the integrated luminosity to 3000fb^{-1} and the instantaneous luminosity up to $7.5\times 10^{34} cm^{โ2} s^{โ1}$ in the ATLAS experiment. This results in an average of 200 proton-proton collisions per bunch-crossing compared to 48 in the current Run-3. This increases radiation damage and device occupancy. To cope...

Hybrid detectors are highly attractive due to their high frame rate, large area coverage, and good radiation tolerance. However, for experiments with soft X-rays (200 eV - 2 keV) they are limited by the poor quantum efficiency of standard silicon sensors and by the low signal-to-noise ratio due to the small signal created by the soft X-ray photons. To overcome these limitations, inverse...

The self-induced signals in trench isolated LGADSs can be driven by the complex interplay of trench-induced defects, electric field distortions, and temperature-dependent carrier dynamics. This self-induced signal phenomenon could be also related to the interplay between the guard ring (GR), trenches, and the n+ bias ring (implanted between two trenches). Such complex relation of many...
