Online aging study of high rate MRPC

TL;DR

This study presents an online aging test of high-rate MRPC detectors under high luminosity conditions, demonstrating stable performance over 36 days of irradiation with no significant degradation.

Contribution

The paper introduces an online aging test system for high-rate MRPC detectors and provides empirical evidence of their stability under prolonged high-luminosity irradiation.

Findings

No significant performance degradation observed after 36 days of irradiation.

Accumulated charge density reached 0.1 C/cm² without affecting detector performance.

Demonstrates the suitability of high-rate MRPCs for long-term high-luminosity experiments.

Abstract

With the constant increase of accelerator luminosity, the rate requirements of the MRPC detectors become important. In the same time, aging problem of the detector has to be studied meticulously. An online aging test system is set up in our Lab. The setup of the system is described and the purpose is to study the performance stability during the long time running under high luminosity environment. The high rate MRPC has been irradiated by X-ray for 36 days and accumulated charge density reached 0.1C/cm2. No obvious performance degradation is observed for the detector.
