The sensor R&D for the future ALICE 3 and ePIC experiment is pushing the knowledge and potential
uses of silicon sensors towards new frontiers, such as in the case of the CMOS Low-Gain Avalanche-Diode (CMOS-LGAD) and Silicon PhotoMultiplier (SiPM) technologies.

At INFN Bologna, the ALICE group is actively involved in the R&D for the Time-Of-Flight (TOF) detector of the future ALICE3...

29. Scaling up test-beam measurements of detector material via multiple scattering with the MONSTAR telescope

Talk

Precise knowledge of detector material for particle detectors is crucial both during the R&D phase and during operation as an input to simulations, in particular for tracking detectors in which both momentum and position resolution are highly sensitive to traversed material. Most past and current projects rely on coarse-grained estimates derived from a nominal design, the accuracy of which can...

35. Time over Threshold Measurments with babyMOSS Beam Telescope

Talk

During the upcoming LHC Long Shutdown 3 the ALICE experiment will upgrade
its 3 Inner Tracking System (ITS2) layers to ITS3. The final design of ITS3 will
have silicon sensors of up to 27 cm × 10 cm, thinned to about 50µm and bent
into a cylindrical shape. The sensor prototypes developed are MOnolithic Stitched
Sensors (MOSS) that are made of 10 Repeated Sensor Units (RSU). A...

1. Sensor modules for the CMS Barrel Timing Layer: new test beam performance results

Claudio Quaranta (Peking University (CN))

Talk

The MIP Timing Detector (MTD) is a new subsystem being developed for the Phase-2 upgrade of the Compact Muon Solenoid (CMS) experiment at the CERN LHC. It is designed to measure the time of arrival of charged particles with a precision of 30–60 ps. This precise timing information will significantly mitigate the effects of the high pileup expected at the High-Luminosity LHC (HL-LHC), thereby...

22. Test beam experiences with Phase 2 CMS BRIL and Inner Tracker: detectors, front-end, back-end, and infrastructure

Talk

The present contribution focuses on the last two years of test beam campaign performed in the context of the CMS Phase 2 luminosity, at the CERN-PS T9 beamline. The systems under test were both the new luminometer Fast Beam Condition Monitor (FBCM), and the new Inner Tracker pixel detectors based on the RD53B ASIC.

The FBCM detector is based on arrays of 6 square silicon pads of the size...

27. Characterization of an Enhanced Lateral Drift (ELAD) Sensor Prototype

Judith Schlaadt

Talk

The development of vertex and tracking detectors for future lepton colliders faces various challenges regarding time and position resolution while maintaining a low material budget and the capability to process high particle rates. In this context, one approach to improve the spatial resolution is to utilise the effect of charge sharing. Here, the charge carriers generated in the sensor volume...

28. Particle Identification based on the Time-over-Threshold with MuPix11 Sensors

Talk

The High-Voltage Monolithic Active Pixel Sensors (HV-MAPS) extend the monolithic design concept by embedding the readout electronics in a deep n-well, enabling high voltage operation and fast charge collection via drift. The MuPix11 is an HV-MAPS chip with a pixel size of 80 x 80 $\mu$m that can be thinned to 50 $\mu$m, offering low material budget and precise spatial and time resolution....

Talk

The crystal Zero Degree Detector (cZDD) is a proposed upgrade to the BESIII experiment in China. In order to measure hadronic cross sections using the Initial State Radiation (ISR) method for a more precise determination of the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon, ISR photons must be detected. Since these photons are predominantly emitted at...
