Title: Initial results on energy resolution of the NEXT-White detector

Journal Article · · Journal of Instrumentation

© 2018 IOP Publishing Ltd and Sissa Medialab. One of the major goals of the NEXT-White (NEW) detector is to demonstrate the energy resolution that an electroluminescent high pressure xenon TPC can achieve for high energy tracks. For this purpose, energy calibrations with 137Cs and 232Th sources have been carried out as a part of the long run taken with the detector during most of 2017. This paper describes the initial results obtained with those calibrations, showing excellent linearity and an energy resolution that extrapolates to approximately 1% FWHM at Qββ.
