Description

REactor neutrino LIquid xenon Coherent Scattering experiment (RELICS) employs the liquid xenon time projection chamber (LXeTPC) technique for the search of neutrino coherent scattering off xenon nuclei (CE$\nu$NS) caused by $\sim$MeV neutrinos emitted from nuclear reactor.Such CE$\nu$NS interactions result in deposit energies of approximately $\sim$keV or sub-keV in LXe, demanding calibrations within the relevant energy ranges.To achieve this, $^{137}$Cs and $^{60}$Co sources will be utilized to calibrate $\gamma$ and $\beta$-induced electronic recoils, while $^{241}$AmBe and a Deuteron-Deuteron (DD) neutron generator will be employed for calibration of CE$\nu$NS.This presentation will focus on simulations of RELICS detector's response using various calibration sources, employing a GEANT4-based toolkit. Notably, it will provide detailed information on the design and simulation of the calibration process for CE$\nu$NS signals with energies ranging from approximately 0.1 to 1.0 keV, by selecting neutron double scatters originating from a collimated DD generator.
