Abstract Within the context of ALICE ITS3 collaboration, a set MAPS small-scale test structures were developed using 65 nm TPSCo CMOS imaging process with upgrade inner tracking system as its primary focus. One such sensor, Circuit Exploratoire (CE-65), and evolution CE-65v2, to explore charge collection properties for varying configurations including layer (standard, blanket, modified gap), pixel pitch (15, 18, 22.5 µm), geometry (square vs hexagonal/staggered). In this work...
The ILD detector is proposed for an electron-positron collider with collision centre-of-mass energies from 90~\GeV~to about 1~\TeV. It has been developed over the last 10 years by international team of scientists goal to design and eventually propose a fully integrated detector, primarily International Linear Collider, ILC. In this report fundamental ideas concepts behind are discussed technologies needed realisation reviewed. document starts short review science goals ILC, how can be...

We describe the planned near-term and potential longer-term upgrades of Belle II detector at SuperKEKB electron-positron collider operating KEK laboratory in Tsukuba, Japan. These will allow increasingly sensitive searches for possible new physics beyond Standard Model flavor, tau, electroweak dark sector that are both complementary to competitive with LHC other experiments.
CMOS Monolithic Active Pixel Sensors (MAPS) have demonstrated their strong potential for tracking devices, particularly flavour tagging. They are foreseen to equip several vertex detectors and beam telescopes. Most applications require high read-out speed, which imposes sensors feature digital output with integrated zero suppression. The most recent development of MAPS at IPHC IRFU addressing this issue will be reviewed. design architecture, combining pixel array, column-level discriminators...

CMOS Monolithic Active Pixel Sensors (MAPS) demonstrate excellent performances in the field of charged particle tracking. A single point resolution 1–2 μm and a detection efficiency close to 100% were routinely observed with various MAPS designs featuring up 106 pixels on active areas as large 4 cm2[1]. Those features make an interesting technology for vertex detectors heavy ion physics. In order adapt sensors high fluxes expected this application, we designed sensor fast column parallel...
