Day 4 - Session 3: Pixel Sensors for Tracking Detectors
- Hiromitsu Takahashi
We have been developing the high-voltage CMOS active pixel sensor, AstroPix, mainly for the future gamma-ray space telescope, AMEGO-X. The gamma-ray detector of AMEGO-X consists of four identical stacked silicon tracker towers and requires $\sim6\times10^4~\rm{cm^2}$ silicon area. The scientific purpose of the AMEGO-X mission dictates a number of requirements on the performances of the...
Monolithic active pixel sensors (MAPS) produced in a 65 nm CMOS imaging technology are being investigated for applications in particle physics. Their main characteristic is integrating a sensing volume and readout circuit in the same silicon wafer, reducing material budget with respect to most hybrid sensors. Compared to the previously investigated 180 nm CMOS imaging technology, the 65 nm...
The proposed Circular Electron Positron Collider (CEPC) presents new challenges for the vertex detector in terms of material budget, spatial resolution, readout speed, and power consumption. To address these challenges, a Monolithic Active Pixel Sensor (MAPS) prototype called TaichuPix has been implemented, which is based on a column drain readout architecture. The TaichuPix sensor chip has...
Detectors based on Chemical Vapor Deposition (CVD) diamond have been used successfully in beam conditions monitors in the highest radiation areas of the LHC. Future experiments at CERN will accumulate an order of magnitude larger fluence. As a result, an enormous effort is underway to identify detector materials that can operate after fluences of 10^{16}/cm^2 and 10^{17}/cm^2. Diamond is one...
