A5: Picosecond Timing Detectors
- Håkan Wennlöf (Deutsches Elektronen-Synchrotron (DESY))
The increase of the particle flux (pile-up) at the HL-LHC with instantaneous luminosities up to L ≃ 7.5 × 1034 cm−2s−1 will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected. A High...
The MIP Timing Detector (MTD) is a new sub-detector planned for the Compact Muon Solenoid (CMS) experiment at CERN, aimed at maintaining the excellent particle identification and reconstruction efficiency of the CMS detector during the High-Luminosity LHC (HL- LHC) era. The MTD will provide new and unique capabilities to CMS by measuring the time-of-arrival of minimum ionizing particles with a...
The aim of the LHCb Upgrade II is to operate at a luminosity of 1.5 x 10$^{34}$ cm$^{-2}$ s$^{-1}$ to collect a data set of 300 fb$^{-1}$. The required substantial modifications of the current LHCb electromagnetic calorimeter due to high radiation doses in the central region and increased particle densities are referred to as PicoCal. A consolidation of the ECAL already during LS3 will reduce...
An innovative single-photon detector based on a vacuum tube with transmission photocathode, a microchannel plate and the Timepix4 CMOS ASIC [[1]] as read-out anode is presented. This photodetector will allow to detect up to 1 billion photons per second over an area of $7\;cm^2$, allowing to simultaneously achieve a position resolution of $5-10\;\mu m$ and a timing resolution better than...
Photek have developed a square microchannel plate (MCP) PMT using 6 µm pore MCPs to achieve superior timing, compared to the previous generation which used 15 µm pores. The native anode pattern is 64x64, but for this module the pattern is ganged to a 16x16 design using an epoxy bonded PCB giving an anode size of 3.3×3.3 mm2 in a 53×53 mm2 active area. The electronic front-end is the TOFPET2d...
