“…This earlier measurement used phenyl xylyl ethane scintillator [17], and set a lower limit for the lifetime of this electron decay mode of 4.6 × 10 26 yr [18]. The work reported here uses a mixture of PC and PPO scintillating solution in the Borexino detector instead.…”

Borexino is a liquid scintillation detector located deep underground at the Laboratori Nazionali del Gran Sasso (LNGS, Italy). Thanks to the unmatched radio purity of the scintillator, and to the well understood detector response at low energy, a new limit on the stability of the electron for decay into a neutrino and a single monoenergetic photon was obtained. This new bound, τ ≥ 6.6 × 10 28 yr at 90% C.L., is 2 orders of magnitude better than the previous limit.

“…PC is currently used as the solvent in the Borexino experiment [32,39] and PXE has been investigated as a back-up solution for the Borexino experiment [40]. The solvent used in KamLAND experiment consists of 20 % PC and 80 % normal dodecane (ND) [12].…”

Spectroscopic study of light scattering in linear alkylbenzene for liquid scintillator neutrino detectors

et al. 2015

View full text Add to dashboard Cite

We have set up a light scattering spectrometer to study the depolarization of light scattering in linear alkylbenzene. The scattering spectra show that the depolarized part of light scattering is due to Rayleigh scattering. The additional depolarized Rayleigh scattering can make the effective transparency of linear alkylbenzene much better than expected. Therefore, sufficient scintillation photons can transmit through large liquid scintillator detector, such as that of the JUNO experiment. Our study is crucial to achieving an unprecedented energy resolution of 3 %/ √ E(MeV) required for the JUNO experiment to determine the neutrino mass hierarchy. The spectroscopic method can also be used to examine the depolarization of other organic solvents used in neutrino experiments.

“…Other purification methods were tested for various liquid scintillators, including water extraction and adsorption 15,16,[19][20][21][22] . Distillation generally separates the solvent and the fluor because they have different boiling points.…”

“…Laboratory tests have been able to give guidance about the effectiveness of different purification methods 19,20,22,35,39,61 , but the laboratory tests cannot measure the level of impurities that are necessary for Borexino. The Borexino detector is the ultimate test of the purification system.…”

“…A description of the CTF and the purification system it employed for PC/PPO scintillator purification is published elsewhere [17][18][19] . More recently an alternative scintillator comprised of PXE (phenyl-o-xylylethane) and PTP (para-Terphenyl) was tested in the CTF 20 . This scintillator mixture was better density matched to water which might have permitted using a water buffer in Borexino.…”

Purification of the 278 tons of liquid scintillator and 889 tons of buffer shielding for the Borexino solar neutrino detector is performed with a system that combined distillation, water extraction, gas stripping and filtration. This paper describes the principles of operation, design, and construction of the purification system, and reviews the requirements and methods to achieve system cleanliness and leak-tightness.
