Tracking, vertexing and timing

Talk

The precision physics program at a Higgs/top/EW factory requires a new generation of vertex detectors, that achieve excellent position and time resolution with a contribution to the material budget of the order of 0.1% of a radiation length per layer. At the same time, the vertex detector must have excellent thermo-mechanical stability. A solution based on CMOS sensors arranged in all-Silicon...

International Large Detector is currently proposed as a measurement concept for the Higgs Factory, which uses Time Projection chamber (ILD-TPC) combined with a gas and an electron amplifier device as the central track detector for momentum measurement. It is necessary to consider the problem that positive ions generated during the generation of ionized electrons distort the electric field in...

3D integrated silicon devices offer the possibility of heterogeneous integration of LGAD sensors with fast-timing readout electronics in 28nm CMOS, potentially enabling a new generation of monolithic timing detectors using 3D integration. Propelled by industry applications, 3D-integration is becoming a well-established technology at semiconductor foundries, making HEP applications possible....

We report on the NAPA (Nanosecond timing Pixel for large Area sensors) detector program—comprising prototype chips NAPA‑p1 and NAPA‑p2—designed for future e⁺e⁻ colliders. We will report on the test results of NAPA‑p1, fabricated in 65 nm CMOS with a 1.5 mm × 1.5 mm footprint and 25 µm pitch as well as the new design of NAPA‑p2. To achieve an improvement in timing resolution and power...

Tracking, vertexing and timing

Talk

The Gas Electron Multiplier (GEM) introduced first time at CERN leverages gas ionization to produce electron ion pair for particle detection It is used in the CMS experiment at the LHC to improve muon detection in the forward region, where high precision and radiation resistance are required. We present the assembly and quality control (QC) tests of GEM detector modules carried out at Panjab...

142. Suitability of a 65 nm CMOS imaging process to reach the position resolution required by a vertex detector at an e+e− future collider

Tracking, vertexing and timing

Talk

The performance of monolithic CMOS pixel sensors strongly depends on the fabrication process,
particularly on the feature size, which directly impacts the achievable pixel pitch.
A consortium led by the CERN EP R&D program, the ALICE experiment,
and various European projects (AIDAinnova, EURIZON) is investigating
the benefits of a 65 nm CMOS imaging process to design a new generation
of...
