Title: Calibration of the NEXT-White detector using 83mKr decays

Abstract

We report the NEXT-White (NEW) detector is currently the largest radio-pure high-pressure xenon gas time projection chamber with electroluminescent readout in the world. It has been operating at Laboratorio Subterraneo de Canfranc (LSC) since October 2016. This paper describes the calibrations performed using 83mKr decays during a long run taken from March to November 2017 (Run II). Krypton calibrations are used to correct for the finite drift-electron lifetime as well as for the dependence of the measured energy on the event transverse position which is caused by variations in solid angle coverage both for direct and reflected light and edge effects. After producing calibration maps to correct for both effects we measure an excellent energy resolution for 41.5 keV point-like deposits of (4.553 +/- 0.010 (stat.) ± 0.324 (sys.)) % FWHM in the full chamber and (3.804 ± 0.013 (stat.) ± 0.112 (sys.)) % FWHM in a restricted fiducial volume. Laslty, using naive 1/$$ \sqrt{E} $$ scaling, these values translate into resolutions of (0.5916 ± 0.0014 (stat.) ± 0.0421 (sys.)) % FWHM and (0.4943 ± 0.0017 (stat.) +/- 0.0146 (sys.)) % FWHM at the Qᵦᵦ energy of xenon double beta decay (2458 keV), well within range of our target value of 1%.
