Pixel detectors are an integral part of medical imaging, particle physics, and many other research areas. Sensors are made from various types of materials such as GaAs, Si, CdTe. Current research tends to use CdTe as X-ray sensors due to its high absorption coefficient in the X-ray spectrum. With decreasing size of pixels, charge diffusion causes charge sharing between neighboring pixels. That...

Modern tracking systems are very precise, therefore, in particle flow-like reconstruction algorithms, the jet performance is usually limited by the calorimeter. The need to solve the fat jet substructure favors the design of finely segmented calorimeters. However, this contrasts with the need to have high temporal resolutions for signal events even at low energy deposits: for example due to...
