Description
Our research at the China Jinping Underground Laboratory (CJPL) has produced significant results from various phases of the 1-ton liquid scintillator neutrino detector. As part of the preliminary phase of the Jinping Neutrino Experiment (JNE), we have investigated its performance at CJPL-I. In 2023, we initiated an upgrade to the 1-ton detector, which primarily involves integrating self-developed electronic systems and 60 MCP-PMTs that we plan to incorporate into JNE.Following this upgrade, the 1-ton detector underwent a series of meticulous tests: first, a Dry-run test phase; next, a pure water operation phase; and finally, a liquid scintillator operation phase. These stages have yielded numerous research outcomes.
In this conference, we will present our latest achievements regarding the 1-ton detector across several key areas: (1) evaluation of the performance and stability of both MCP-PMTs and self-developed electronic systems; (2) assessment of operational performance during the pure water and liquid scintillator phases; (3) results of muon flux measurement obtained from the pure water phase; and (4) timing and energy calibration of the upgraded detector.
