AI 中文摘要
ATLAS缪子漂移管室的读出电子学将为高亮度大型强子对撞机（HL-LHC）的运行进行升级，升级的一部分是引入新型放大器-成形-鉴别器（Amplifier-Shaper-Discriminator）芯片。本说明利用在单能高能缪子束中运行的小直径缪子漂移管室的数据，针对原初电子信号开展新型芯片鉴别器阈值的校准工作。拟用于ATLAS缪子谱仪的鉴别器阈值对应20个原初电子的信号。
英文摘要
The read-out electronics of the ATLAS muon drift-tube chambers will be upgraded for operation at the High-Luminosity Large Hadron Collider. Part of the upgrade is the introduction of new amplifier-shaper-discriminator chips. This note presents the calibration of the discriminator threshold of the new chip in terms of primary electron signals using data from small-diameter muon drift-tube chambers operated in a monoenergetic, high-energy muon beam. The discriminator threshold intended for use in the ATLAS muon spectrometer corresponds to the signal of 20 primary electrons.
