During Run 3 and 4 ALICE (A Large Ion Collider Experiment) will gain two orders of magnitude in the statistics over the combined data collected during Run 1 and Run 2 at the LHC. ALICE will also conduct high-precision measurements of rare probes over a broad range of transverse momenta with particular focus on low signal-to-background probes at low pT values. To achieve that goal a sustained...
The physics aims at the proposed future CLIC high-energy linear e+e- collider pose challenging demands on the performance of the detector system. In particular the vertex and tracking detectors have to combine precision measurements with robustness against the expected high rates of beam-induced backgrounds. A spatial resolution of a few microns and a material budget down to 0.2% of a...
The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). In particular, a new timing layer will measure minimum ionizing particles (MIPs) with a time resolution of ~30ps and hermetic coverage up to a pseudo-rapidity of |η|=3. This MIP Timing...
The LHCb Upgrade I, currently under construction and scheduled to start data taking in Run 3, will transform the experiment to a triggerless system reading out the full detector at 40 MHz event rate. The increased luminosity and trigger efficiency anticipated at the upgrade will allow a huge increase in precision, in many cases to the theoretical limit, and the ability to perform studies...
The Silicon Photomultiplier (SiPM) is a solid-state device capable of sensing, timing
and quantifying with high accuracy light signals down to the single-photon level.
Featuring large internal gain with negligible fluctuations, high intrinsic timing resolution,
low-voltage operation, insensitivity to magnetic fields, high degree of radio-purity,
mechanical robustness and excellent...
Scintillator based radiation detectors readout by SiPMs successively break records in their reached time resolution. Nevertheless, new challenges in time of flight positron emission tomography (TOF-PET) and high energy physics are setting unmatched goals in the 10ps range. Recently we have shown that high frequency (HF) readout of SiPMs significantly improves the measured single photon time...
A positron timing counter (TC) required 30-40 ps time resolution for ~50 MeV/c positron by the MEG II experiment has been developed. We employed the high segmented design with 512 scintillator plates ($120 \times 40 \times 5$ mm$^3$ and $120 \times 50 \times 5$ mm$^3$) attached 6-SiPM-array at the both ends. Pile up is reduced by the segmented design, and multi-counter measurement improves the...
