“…The design [14] and R&D program [15] for the 20-inch PMT electronics have been driven by requirements of reconstructing the deposited energy in the LS with high resolution and a good linearity response over a wide dynamic range: from 1 p.e. for low energy events to 1000 p.e.…”

“…Since it is almost impossible to repair the 'wet' electronics underwater in the water pool during operation, its loss rate is required to be < 0.5% in 6 years. This requirement has generated important constraints on the reliability of the 'wet' electronics (see the discussion in [15]). As can be seen from Fig.…”

“…2, three PMT output signals are fed to the front-end and readout electronics located inside the UWbox. The PMT high voltage is provided for each PMT by a custom High Voltage module [15] located inside the UWbox. The analog signal is amplified and converted to digital with a 14 bit, 1 GS/s, custom ADC.…”

The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment currently under construction in South China, expecting to start data taking in 2023. JUNO primary goal is the determination of the neutrino mass ordering and the measurement, at a sub-percent level, of three of the neutrino oscillation parameters . The main detector, placed in a cavern about 700 m underground (1800 m.w.e.), will consist of 20 kton of liquid scintillator contained in a 35.4 m diameter acrylic sphere, becoming the largest detector of its kind ever built in the world. JUNO will be instrumented with 17,612 20-inch photomultiplier tubes (PMTs), and 25,600 3-inch PMTs reaching a photo-coverage above 75%. The experiment will achieve an unprecedented energy resolution of 3%/ E(MeV) thanks to a comprehensive calibration system, among others. The acrylic sphere will be submerged in a water Cherenkov detector and covered on the top by layers of plastic scintillator to tag cosmic ray muons, a major source of background. This paper will review the physics potential of JUNO as a medium baseline reactor anti-neutrino experiment, illustrate the technical characteristics of the detector, discuss the technological challenges and present the construction status.

The design and sensitivity of JUNO’s scintillator radiopurity pre-detector OSIRIS

et al. 2021

View full text Add to dashboard Cite

The OSIRIS detector is a subsystem of the liquid scintillator filling chain of the JUNO reactor neutrino experiment. Its purpose is to validate the radiopurity of the scintillator to assure that all components of the JUNO scintillator system work to specifications and only neutrino-grade scintillator is filled into the JUNO Central Detector. The aspired sensitivity level of $$10^{-16}\hbox { g/g}$$ 10 - 16 g/g of $$^{238}\hbox {U}$$ 238 U and $$^{232}\hbox {Th}$$ 232 Th requires a large ($$\sim 20\,\hbox {m}^3$$ ∼ 20 m 3 ) detection volume and ultralow background levels. The present paper reports on the design and major components of the OSIRIS detector, the detector simulation as well as the measuring strategies foreseen and the sensitivity levels to U/Th that can be reached in this setup.

“…The main challenge of the whole electronics system is the very strict criteria on reliability: a maximum of 0.5% failure over 6 years for the PMT full readout chain, as well as the large data transfer of 1.25 Gb/s that needs to be delivered over 2 times 100 m Ethernet cables. A detailed description of the full electronics chain of JUNO, from the PMTs front-end to the trigger and DAQ is presented in [3]. For the front-end electronics, the global control unit (GCU) [4] will digitize the incoming analog signals with custom designed high speed ADU (analog to digital converter unit).…”
