Abstract

The high magnetic field (HiFi) muon instrument at the ISIS pulsed neutron and muon source is a state-of-the-art spectrometer designed to provide applied magnetic fields up to 5 T for muon studies of condensed matter and molecular systems. The spectrometer is optimised for time-differential muon spin relaxation studies at a pulsed muon source. We describe the challenges involved in its design and construction, detailing, in particular, the magnet and detector performance. Commissioning experiments have been conducted and the results are presented to demonstrate the scientific capabilities of the new instrument.

摘要

位于 ISIS 脉冲中子与μ子源的高磁场（HiFi）μ子仪器是一台先进的光谱仪，旨在为凝聚态物质和分子系统的μ子研究提供高达 5 T 的外加磁场。该光谱仪针对脉冲μ子源的时间分辨μ子自旋弛豫研究进行了优化。我们描述了其设计和建造过程中所面临的挑战，尤其详细介绍了磁体和探测器的性能。已经开展了调试实验，并展示结果以证明这台新仪器的科学能力。
