Pixel for X-ray imaging

ORAL

High energy radiation like X rays and Minimum Ionizing Particles (MIPs) have a radiation length of several tens of microns in silicon. When using standard CMOS processes with low-resistivity silicon substrates or thin high-resistivity EPI layers, the achievable signal amplitude is too small to provide competitive performance for applications in particle tracking or low energy X-ray detection....

In view of applications in the tracking detectors of the ATLAS High Luminosity LHC (HL-LHC) upgrade, we have developed a new generation of High Voltage CMOS (HV-CMOS) monolithic pixel-sensor prototypes featuring the AMS aH18 (180 nm) commercial CMOS technology. By fully integrating both analog and digital readout-circuitry on the same particle-detecting substrate, current challenges of hybrid...

Pixel sensor technology

ORAL

CMOS sensors with a small collection electrode are attractive for a wide range of applications due to the very low sensor capacitance allowing for a very low noise and analogue power consumption. Such sensors have been studied and developed for the ALICE ITS upgrade, where they have been selected as the technology of choice. To achieve a full lateral depletion in the sensor, a process...

We summarize the characterization status for two different depleted monolithic CMOS active pixel sensor (DMAPS) prototypes with a fully synchronous column-drain read-out architecture: LF-Monopix and TJ-Monopix. These chips are part of a joint effort aiming towards a suitable implementation of a radiation-hard DMAPS with a fast readout architecture for the HL-LHC ATLAS Inner Tracker (ITk)...

The Circular Electron Positron Collider (CEPC) is proposed as a Higgs factory, targeting a high precision study of the properties of the Higgs boson. To achieve the required sensitivity of experiment, the CEPC vertex detector should provide unprecedented position resolution with very low material budget, and low power consumption. CMOS Pixel Sensors (CPS), as one of the promising candidate...

Monolithic active pixel sensors (MAPS) based on commercial
high-voltage CMOS processes are an exciting technology that is
considered as an option for the ATLAS inner tracker upgrade. Here,

The proposed Circular Electron Positron Collider (CEPC) will allow measurement of the Higgs properties with precision beyond the (HL-)LHC. To meet the stringent physics requirements, its vertex detector will have to be constructed with the state-of-the-art pixel detector technologies that promise high spatial resolution, low power consumption and low material budget. We have conducted R&D...
