Synthesis of Deuterated Benzene(C₆D₆) liquid scintillator for nuclear and high energy physics experiments

Liquid scintillation detectors are widely employed in both nuclear physics and high energy physics experiments for neutron and neutrino spectroscopy due to their relatively high light output, fast time response, pulse shape discrimination and possibility of loading metals of suitable isotopes for rare event searches. The main objective of the DLS collaboration is to develop liquid scintillator (LS), metal loaded LS for the measurement of neutrons and neutrinos from various sources(solar, reactor, supernovae etc.) and planning to make 1 ton detector as prototype and subsequently develop 1 kton LAB or deuterated LS for neutrino physics. A deuterated liquid scintillator (DLS) is sensitive to both Charge Current from both ν_e and ν¯_e and Neutral Currents events from all flavors. It has ability to measure the low energy neutrino spectrum. We present results of a deuterated benzene (C₆D₆) based LS detector using C₆D₆, which to our knowledge has been done for the first time in the country. We also characterised this detector in terms of its scintillation light yield and pulse shape discrimination response
