Title: Cherenkov and scintillation light separation in organic liquid scintillators

Abstract

The CHErenkov/Scintillation Separation experiment (CHESS) has been used to demonstrate the separation of Cherenkov and scintillation light in both linear alkylbenzene (LAB) and LAB with 2 g/L of PPO as a fluor (LAB/PPO). This is the first successful demonstration of Cherenkov light detection from the more challenging LAB/PPO cocktail and improves on previous results for LAB. A time resolution of 338 ± 12 ps FWHM results in an efficiency for identifying Cherenkov photons in LAB/PPO of 70 ± 3 % and 63 ± 8 % for time- and charge-based separation, respectively, with scintillation contamination of 36 ± 5 % and 38 ± 4 %. LAB/PPO data is consistent with a rise time of τ_r = 0.72 ± 0.33 ns.

Experiment to demonstrate separation of Cherenkov and scintillation signals

Journal Article Caravaca, J. ; Descamps, F. B. ; Land, B. J. ; ... - Physical Review. C

The ability to separately identify the Cherenkov and scintillation light components produced in scintillating mediums holds the potential for a major breakthrough in neutrino detection technology, allowing development of a large, low-threshold, directional detector with a broad physics program. The CHESS (CHErenkov/Scintillation Separation) experiment employs an innovative detector design with an array of small, fast photomultiplier tubes and state-of-the-art electronics to demonstrate the reconstruction of a Cherenkov ring in a scintillating medium based on photon hit time and detected photoelectron density. This paper describes the physical properties and calibration of CHESS along with first results. The ability to reconstruct Cherenkovmore »« less

Characterization of water-based liquid scintillator for Cherenkov and scintillation separation

Journal Article Caravaca, J. ; Land, B. J. ; Yeh, M. ; ... - European Physical Journal. C, Particles and Fields

This paper presents measurements of the scintillation light yield and time profile for a number of concentrations of water-based liquid scintillator, formulated from linear alkylbenzene (LAB) and 2,5-diphenyloxazole (PPO). We find that the scintillation light yield is linear with the concentration of liquid scintillator in water between 1 and 10% with a slope of 127.9±17.0 ph/MeV/concentration and an intercept value of 108.3±51.0 ph/MeV, the latter being illustrative of non-linearities with concentration at values less than 1%. This is larger than expected from a simple extrapolation of the pure liquid scintillator light yield. The measured time profiles are consistently faster thanmore »« less

Separation of scintillation and Cherenkov lights in linear alkyl benzene

Journal Article Li, Mohan ; Guo, Ziyi ; Yeh, Minfang ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

To separate scintillation and Cherenkov lights in water-based liquid scintillator detectors is a desired feature for future neutrino and proton decay experiments. Linear alkyl benzene (LAB) is one important ingredient of a water-based liquid scintillator currently under development. In this paper we report on the separation of scintillation and Cherenkov lights observed in an LAB sample. The rise and decay times of the scintillation light are measured to be (7.7±3.0)ns and (36.6±2.4)ns, respectively, while the full width [–3σ, 3σ] of the Cherenkov light is 12 ns and is dominated by the time resolution of the photomultiplier tubes. Here, the scintillationmore »« less

Slow liquid scintillator candidates for MeV-scale neutrino experiments

Journal Article Guo, Ziyi ; Yeh, Minfang ; Zhang, Rui ; ... - Astroparticle Physics

Slow liquid scintillator Cherenkov detectors have been proposed as part of several future neutrino experiments because they can provide both directionality and energy measurements. This feature is expected to enhance the sensitivities for MeV-scale neutrino physics, including solar physics, the search for supernova relic neutrino, and the study of geo-sciences. In this study, the characteristics of a slow liquid scintillator were investigated, along with the light yields and decay time constants for various combinations of linear alkylbenzene (LAB), 2,5-diphenyloxazole (PPO), and 1,4-bis (2-methylstyryl)-benzene (bis-MSB). Here, the results of our study indicated that LAB with 0.07 g/L of PPO and 13more »« less

Cherenkov and scintillation separation in water-based liquid scintillator using an LAPPDTM

Journal Article Kaptanoglu, T. ; Callaghan, E. J. ; Yeh, M. ; ... - European Physical Journal. C, Particles and Fields

This manuscript describes measurements of water-based liquid scintillators (WbLS), demonstrating separation of the Cherenkov and scintillation components using a low energy β source and the fast timing response of a Large Area Picosecond Photodetector (LAPPD). Additionally, the time profiles of three WbLS mixtures, defined by the relative fractions of scintillating compound, are characterized, with improved sensitivity to the scintillator rise-time. The measurements were made using both an LAPPD and a conventional photomultiplier tube (PMT). All samples were measured with an effective resolution O(100 ps), which allows for the separation of Cherenkov and scintillation light (henceforth C/S separation) by selecting onmore »« less
