Description
The RENE (Reactor Experiment for Neutrinos and Exotics) experiment aims to search for sterile neutrinos in theΔm² ≈ 2 eV² region at a baseline of about 23 m from the reactor core. The prototype detector consists of a 0.5-ton cylindrical target filled with 0.5% gadolinium-loaded liquid scintillator (GdLS), surrounded by a 1.5-ton box-shaped gamma catcher with liquid scintillator (LS). The active volume is instrumented with two 20-inch photomultiplier tubes (PMTs). The detector is currently in the assembly and commissioning stage at a ground-level laboratory, where we are testing system stability and verifying operational readiness. As part of this commissioning process, performance studies have been carried out using calibration data and radioactive sources, providing insight into the detector’s energy response, calibration procedures, and background characterization. In this study, we performed a three-dimensional calibration using radioactive sources to evaluate the overall performance of a liquid scintillator based neutrino detector. Data collected at various positions inside the detector were used to examine the energy response and its position dependence, which were subsequently corrected to ensure a uniform response throughout the full detector volume. In this presentation, we will describe the calibration procedure, the obtained results, and how these have been applied to evaluate and improve the detector performance.
