Oral

In the coming years the Large Hadron Collider (LHC) at CERN is being upgraded to work at higher luminosities, leading to the High-Luminosity LHC. The HL-LHC will reach luminosities up to 5 × 10$^{34}$ cm$^{−2}$ s$^{−1}$ collecting at least 3000 fb$^{−1}$ of data in its lifetime. To handle the increased luminosity and data rate, the experiments at the LHC will be upgraded as well. One of the...

CMOS

Oral

The goal for tracking detectors is the combination of excellent spatial resolution, low material budget, high radiation tolerance and excellent timing resolution for the best achievable tracking performance.
Many different approaches are taken to reach this goal, with CMOS based silicon detectors providing one of the most promising angles of approach.

The CERN RD50 collaboration works on...

28. Design and performance of UKRI-MPW0: an HV-CMOS prototype with a novel sensor cross-section

CMOS

Oral

The High Voltage CMOS (HV-CMOS) technology is a promising candidate for future particle physics experiments. To meet the needs of future experiments, especially in terms of single point resolution ($50 \times 50 \mathrm{\mu m^2}$), time resolution (0.2 ns) and radiation tolerance ($10^{16} \mathrm{n_{eq}/cm^2}$), the HV-CMOS pixel sensor performance needs to be further improved. The Liverpool...

18. A CMOS pixels upgrade for the Belle II Vertex Detector

Ludovico Massaccesi

CMOS

Oral

The success of the Belle II experiment at KEK (Tsukuba, Japan) relies on the very high instantaneous luminosity expected from the SuperKEKB collider in the coming years, close to $6\times10^{35}\ \mathrm{cm}^{-2}\ \mathrm{s}^{-1}$. The beam conditions required to reach such luminosity cause a large rate of background particles to reach the innermost layers of the Belle II detector, which...
