JUNO is a huge neutrino detector that will use 20 kton of organic liquid scintillator as its detection medium. The mixture linear alkyl benzene (LAB), 2.5 g/L 2,5-diphenyloxazole (PPO) and 3 mg/L 1,4-Bis(2-methylstyryl)benzene (Bis-MSB). main goal to determine the Neutrino Mass Ordering [1, 2, 3]. In order achieve this purpose, good energy position reconstruction required, hence complete understanding optical characteristics mandatory. paper we present measurements on emission spectrum,...
Abstract Gravimetric methods are expected to play a decisive role in geophysical modeling of the regional crustal structure applied geoneutrino studies. GIGJ (GOCE Inversion for Geoneutrinos at JUNO) is 3‐D numerical model constituted by ~46 × 10 3 voxels 50 0.1 km, built inverting GOCE (Gravity field and steady‐state Ocean Circulation Explorer) gravimetric data over 6° 4° area centered JUNO (Jiangmen Underground Neutrino Observatory) experiment, currently under construction Guangdong...
Large-area PhotoMultiplier Tubes (PMT) allow to efficiently instrument Liquid Scintillator (LS) neutrino detectors, where large target masses are pivotal compensate for neutrinos' extremely elusive nature. Depending on the detector light yield, several scintillation photons stemming from same interaction likely hit a single PMT in few tens/hundreds of nanoseconds, resulting photoelectrons (PEs) pile-up at anode. In such scenario, signal generated by each PE is entangled others, and an...
This article describes a design of an field-programmable gate array (FPGA) implementation clock and data recovery (CDR) system. The core will be integrated in the FPGA configuration for front-end electronics (FEE) board Jiangmen underground neutrino observatory (JUNO) experiment. placed on main detector, underwater, making not accessible after installation. timing trigger system relies synchronous link connection over CAT5e cable (up to 100 m long) between back-end (BEE), where twisted-pair...
In the field of rare event physics, it is common to have huge masses organic liquid scintillator as detection medium. particular, they are widely used study neutrino properties or astrophysical neutrinos. Thanks its safety (such low toxicity and high flash point) easy scalability, linear alkyl benzene most solvent produce scintillators for large mass experiments. The knowledge refractive index a pivotal point understand detector response, this quantity (and wavelength dependence) affects...
The optical and radiochemical purification of the scintillating liquid, which will fill central detector JUNO experiment, plays a crucial role in achieving its scientific goals. Given gigantic mass dimensions an unprecedented target value about 3% @ 1 MeV energy resolution, has set severe requirements on parameters scintillator, such as attenuation length (Lat>20 m at 430 nm), transparency, light yield, content radioactive contaminants (238U,232Th<10-15 g/g). To accomplish these needs,...
Several neutrino detectors, KamLAND, Daya Bay, Double Chooz, RENO, and the forthcoming large-scale JUNO, rely on liquid scintillator to detect reactor antineutrino interactions. In this context, inverse beta decay represents golden channel for detection, providing a pair of correlated events, thus strong experimental signature distinguish signal from variety backgrounds. However, given low cross-section interactions, development powerful event selection algorithm becomes imperative achieve...

It is generally inferred from astronomical measurements that Dark Matter (DM) comprises approximately 27\% of the energy-density universe. If DM a subatomic particle, possible candidate Weakly Interacting Massive Particle (WIMP), and DarkSide-50 (DS) experiment direct search for evidence WIMP-nuclear collisions. DS located underground at Laboratori Nazionali del Gran Sasso (LNGS) in Italy, consists three active, embedded components; an outer water veto (CTF), liquid scintillator (LSV), argon...
The existence of dark matter is known because its gravitational effects, and although nature remains undisclosed, there a growing indication that the galactic halo could be permeated by weakly interactive massive particles (WIMPs) with mass order 100 GeV. Direct observation WIMP-nuclear collisions in laboratory detector plays key role searches. However, it also poses significant challenges, as expected signals are low energy very rare. DarkSide project for direct WIMPs liquid argon...
Nuclear reactors are a source of electron antineutrinos due to the presence unstable fission products that undergo $\beta^-$ decay. They will be exploited by JUNO experiment determine neutrino mass ordering and get very precise measurements oscillation parameters. This requires reactor antineutrino spectrum characterized as precisely possible both through high resolution measurements, foreseen TAO experiment, detailed simulation models. In this paper we present benchmark analysis utilizing...
