摘要

本文介绍了为保护ESS溅射靶而开发的探测器。安装该探测器的目的是接收峰值电流为 62.5 mA、平均功率为 5 MW、能量高达 2 GeV 的质子束。它的设计目的是探测质子束超出限定孔径的任何部分,这种情况被视为质子束异常。该探测器主要用于机器保护。探测器的工作基于两个物理过程。第一个过程是在金属叶片中产生电流,该电流与截获的光束成正比。第二个过程是光束能量沉积在相互作用的热电偶中产生的热负荷。将这两种信号结合起来,可以检测从微秒到几分钟的事件。本文还介绍了仪器的设计、效率和工作范围。

Proton Beam APerture MoniTor instrument design and overview for the Commissioning and Operation of ESS High Power Beam on Target
This paper presents a detector developed to protect the ESS spallation target. The detector is installed to receive a proton beam that has a peak current of 62.5 mA, an average power of 5 MW, and energy up to 2 GeV. It is designed to detect any part of the proton beam that goes outside a defined aperture, which is deemed as an errant beam condition. This detector is mainly used for machine protection. The detector works based on two physical processes. The first process is the generation of current in metallic blades, which is proportional to the intercepting beam. The second process is heat load from the beam energy deposition in interacting thermocouples. The combination of these two signals allows the detection of events ranging from microseconds to several minutes. This paper also presents the design of the instrument, its efficiency, and its range of operation.
