The response of the recently developed Tl 2 LiYCl 6 (Ce) scintillator to neutrons was measured and the 35Cl(n,p) channel observed in the material for the first time. The scintillator was exposed to a 252Cf source mounted within a parallel-plate avalanche counter for fission-fragment coincident measurements. Proton- and t + α -like events are selected with the pulse-shape discrimination technique. Comparison of energy-deposition and time-of-flight allows the quenching of the different channels to be assessed. The 6Li(n,t) α channel is found to have its energy quenched to 37(1)% relative to γ -ray detection, while the proton energy deposition spectrum is quenched to 60(1)%. [ABSTRACT FROM AUTHOR]

NeutronSTARS ( Neutron - S ilicon T elescope A rray for R eaction S tudies) consists of 2.2-tons of gadolinium-doped liquid scintillator for neutron detection and large area silicon detectors for charged particle identification. This detector array is intended for low-energy-nuclear-reaction measurements that result in the emission of neutrons such as ( n , x n ) and fission. This paper describes the NeutronSTARS experimental setup, calibration, and the array’s response to neutral and charged particles. [ABSTRACT FROM AUTHOR]
