B2: Neutrino Detectors
- sen Qian (IHEP,CAS)
The long baseline T2K neutrino experiment in Japan obtained a first indication of CP violation in neutrino oscillations. To obtain better sensitivity, T2K will accumulate more statistics with a higher intensity beam and the upgraded near detector ND280 which allows us to reduce systematic uncertainties in oscillation measurements. The upgraded detector will have the full polar angle...
The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector being built for neutrino detection. The detector will be built in a laboratory at 700-m underground for cosmic muon-induced background reduction. The 20 kton of liquid scintillator target is in an acrylic sphere surrounded by 17612 20-inch large PMTs that compose the central detector. A 34 kton...
The Water Cherenkov Test Experiment (WCTE) is a CERN experiment that aims to test several technologies and techniques related to water Cherenkov detectors. It will consist of approximately 120 multi-PMT photosensors placed in a water tank (~3.8 m diameter, ~3.6 m height, total water mass ~41 tonnes). Each multi-PMT consists of nineteen 3” PMTs and the associated front-end electronics enclosed...
Hyper-Kamiokande (HK) is a next generation underground water Cherenkov detector to be built in Japan for neutrino oscillation studies, proton decay searches, and neutrino astrophysics. An Outer Detector (OD) will provide information to identify interactions originating from particles outside the inner detector of HK and to veto background events. The baseline configuration of OD includes a...
About 25 thousand 3-inch PMTs (SPMTs) were designed to install in JUNO detector between the gaps of about 18 thousand 20-inch PMTs (LPMTs) to enhance the detector performance, such as improving energy resolution and nonlinearity, extend JUNO physics like supernova neutrino detection and so on. Currently, all the parts of SPMT system, such as SPMTs, cables, electronics and under water boxes...
