Mass production and characterization of 3-inch PMTs for the JUNO experiment

Journal: :Nuclear Instruments and Methods in Physics Research 2021

26,000 3-inch photomultiplier tubes (PMTs) have been produced for Jiangmen Underground Neutrino Observatory (JUNO) by the Hainan Zhanchuang Photonics Technology Co., Ltd (HZC) company in China and passed all acceptance tests with only 15 rejected. The mass production began 2018 elapsed about 2 years at a rate of $\sim$1,000~PMTs per month. characterization PMTs was performed factory concurrentl...

Start of Things for Kamiokande: Kamioka Nucleon Decay Experiment

Journal: :Progress of theoretical and experimental physics 2022

Abstract In 1980, detecting the evidence of so-called Grand Unified Theory (GUT) became a major challenge for experimentalists. The GUT predicted that protons would decay, and M. Koshiba proposed Kamioka Nucleon Decay Experiment (Kamiokande), which was originally conceived designed detection proton decay signals. Kamiokande 3000-t water Cherenkov detector located 1000 m underground in mine. uni...

A Comparison of PET Detector Modules Employing Rectangular and Round Photomultiplier Tubes

2004

Simon R. Cherry Martin P. Tornai Craig S. Levin Stefan Siegel Edward J. Hoffman C. W. Williams

We have compared the high resolution BGO detector blocks from the EXACT HR PET system which use two dual-cathode rectangular photomultiplier (PM) tubes with a new block design, the EXACT HR PLUS, which uses four round PM tubes. Despite the lower coupling area between photocathode and scintillator, the HR PLUS block compares favorably with the HR block. The energy resolution averages 20% for the...
