The entire tracking system of the ATLAS experiment will be replaced in 2025 during the LHC Phase-II shutdown by an all-silicon detector called the “ITk” (Inner Tracker). The innermost part of ITk will be a pixel detector containing about 12.5m2 of sensitive silicon. The silicon modules are arranged on 5 layers of stave-like support structures in the most central region and ring-shaped...
In the recent development of pixel detector for the inner part of ATLAS detector upgrade of the High Luminosity LHC, thin planar pixel detector has been developed. To reduce hit occupancy, pixel size is smaller than currently operating pixel detector in ATLAS and the 2 options, 50um x 50um and 25um and 100um, are considered by the same 50um x 50um pitch readout ASIC. To evaluate the performace...
Readout chips for the HL-LHC upgrades have to address enormous challenges in terms of data throughput and radiation levels, ionizing and non-ionizing, that harm the sensing and readout parts of pixel detectors alike. Advances in microelectronics and microprocessing technologies now enable large scale detector designs with unprecedented performance in measurement precision (space and time)....
This paper presents a SOI pixel(SOIPIX) detector using pinned depleted diode structure suitable for high-energy-resolution X-ray imaging and high-sensitivity NIR imaging. The pinned depleted diode(PDD) structure greatly reduces the R-G dark current generation at the SOI back-gate and the read noise thanks to the very small sensing capacitance and improves the charge correction efficiency. This...
