Multichannel plate photon detectors (MCP-PMTs) have excellent intrinsic time resolutions of order 50 picoseconds. Large area picosecond PMTs were initiated in 2009 by the LAPPD collaboration and these devices are now commercially produced at Incom Inc. LAPPDs can be operated at high gain, have single photon sensitivity low dark count rates and good quantum efficiency, and thus are a promising...
Metamaterials have great promise to produce highly tunable radiators for particles to interact with. Such radiators would have uses in PID detectors any beyond. This talk will discuss some of the possible structures, and some of their potentially interesting uses. As well as some initial studies.
COMPASS and LHCb use C_4F_10 and CF_4 Cherenkov gas radiators. These Saturated FuoroCarbons (Cn_F(2n+2)) have high GWPs, however (5000-9000*CO_2) so there is impetus to reduce their consumption.
Oxygenated fluorocarbons (C_nF_2nO) can offer similar optical performance, with GWPs equivalent to CO2. Their GWPs are geometry-specific however: closed molecular rings containing an oxygen atom link...
Simulation of optical photons take a significant amount of CPU time in many HEP experiments. GPUs have been used efficiently by the industry for ray tracing photons. Recently the JUNO neutrino experiment showed that a speedup factor of 1650 in the simulation of a Cherenkov detector can be achieved using GPUs. This level of improvement is impossible to obtain by other means.
The software...
A compact and modular ring imaging Cherenkov (mRICH) detector has been developed to provide K/$\pi$ separation over a momentum coverage of 3 to 10 GeV/c, and an e/$\pi$ separation of up to 2.5 GeV/c within the Electron-Ion Collider Generic R&D Consortium. The mRICH detector consists of an aerogel block, a Fresnel lens, a flat-mirror set, and a photosensor plane. The first prototype of this...
