从ALICE μ子触发器/鉴别器探测器获得的电阻板室老化经验
Experience gained about Resistive Plate Chambers ageing from the ALICE Muon TRigger/IDentifier detector
摘要：
ALICE μ子鉴别器由72个单间隙酚醛树脂电阻板室组成，自2009年以来一直在使用四氟乙烷/异丁烷/六氟化硫混合气体的最大雪崩模式（鉴别阈值：7 mV，无放大）下运行，计数率为数十Hz/cm ^2。在这次演讲中，RPC系统的长期性能和稳定性将在效率，暗电流和暗速率方面进行讨论。将对探测器上观察到的潜在老化迹象进行评估，并总结最常见的硬件问题。
英文摘要：
The ALICE Muon IDentifier is composed of 72 single-gap bakelite Resistive Plate Chambers, which have been operational since 2009 in maxi-avalanche mode (discrimination threshold:7 mV without amplification) with a Tetrafluoroethane/Isobutane/Sulfur Hexafluoride gas mixture, undergoing counting rates of the order of tens of Hz/cm^2. In this talk, the long-term performance and stability of the RPC system will be discussed, in terms of efficiency, dark current and dark rate. An assessment of potential signs of ageing observed on the detectors will be presented, together with a summary of the most common hardware problems experienced.
