In order to cope with 5-10 times higher instantaneous luminosities at the LHCb detector, a large Scintillating Fibre Tracker has been developed to replace the tracking detectors downstream of the dipole magnet. This detector is currently being installed and will be commissioned after the Long Shutdown 2 (LS2) of the LHC in 2021.
The detector is based on plastic scintillating fibres read out by...
The DUNE (Deep Underground) experiment will bring the technology of Liquid Argon TPC to an unprecedented size in order to study neutrino oscillations at very long baselines and establish CP violation in the leptonic sector. The observation of the VUV photons from the scintillation of Argon plays a prominent role in the DUNE physics programme and requires the development of a novel Photon...
The ERC funded ENUBET project is developing detectors suitable for positron reconstruction in the decay tunnel of a narrow band beam to monitor at 1% level the neutrino flux from the three-body semileptonic decays of kaons. The baseline option for the tunnel instrumentation employs a fine-grained shashlik calorimeter with a 4.3 $X_{0}$ longitudinal segmentation to separate positrons and pions...
The capability to detect faint light events at few photon level is of extreme importance for a number of application ranging from base research to medicine, to industry as well as daily life needs. Until few years ago, photon counting was synonym of Photomultiplier Tube and Solid State devices were considered not sensitive enough for this demanding use. Since the introduction of SPADs and...
Taishan Antineutrino Observatory (TAO) is a ton scale liquid scintillator (LS) detector and proposed to precisely measure reactor neutrino energy spectrum with as high as possible energy resolution, which can provide a reference spectrum for Jiangmen Underground Neutrino Observatory (JUNO) and a benchmark to verify the nuclear database. Tao is a satellite experiment of JUNO and will be...
Silicon photo-multipliers (SiPMs) have been chosen for detecting liquid Xenon scintillation light in the nEXO experiment being designed to search for neutrinoless double beta decay. SiPMs from FBK and Hamamatsu more or less fulfill nEXO's specifications achieving more than 15% photo-detection efficiency (PDE) at 175nm. However, the interplay between PDE, reflectivity (as high as 55% at 175nm),...
The design of the CMS phase II upgrade for the SHLC uses SiPMs for the Barrel Timing Layer (BTL) and the Behind HCAL detector (BH). In both sub-detectors the SiPMs will see a 1 MeV Equivalent dose of around 10E14 n/cm2. To lower the noise in the SiPMs the design is to run at a low temperature of -30C .
Different samples from two manufactures of SiPMs were radiated up to a very high total...
