This proposal is a request for a high-field/high-homogeneity superconducting magnet to be used for muon spin rotation (muSR) studies of advanced materials at the Centre for Molecular and Materials Science (CMMS) at TRIUMF. The behaviour of materials under the influence of high magnetic fields provides a window into understanding the physics of complex phenomena at a subatomic or quantum level. The proposed 9 T, 10 ppm magnet will be used on the newly constructed M20 surface muon beam line, where it will support a unique research instrument. In particular, it will provide the cohort of Canadian and international users of the CMMS facility with the capability to measure muSR signals in samples subjected to high magnetic field over a time range that is twice as long as what is possible anywhere else in the world. The combination of high magnetic field and a long muSR time window will among other things, facilitate investigations of competing orders, enable determination of local spin susceptibilities, and allow for studies of high-field slow relaxation phenomena.

该提案是要求在Triumf的分子和材料科学中心（CMMS）的高级旋转旋转（MUSR）研究的高场/高均匀性超导磁铁。在高磁场的影响下材料的行为为理解亚原子或量子水平的复杂现象的物理学提供了一个窗口。提出的9吨，10 ppm磁铁将在新建的M20表面亮束线上使用，在那里它将支持独特的研究仪器。特别是，它将为CMMS设施的加拿大和国际用户提供同类，并在一个时间范围内测量具有高磁场的MUSR信号，该样品的时间范围是世界其他任何地方的可能性是两倍。高磁场和较长的MUSR时间窗口的组合将有助于研究竞争订单，能够确定局部自旋敏感性，并允许研究高场慢的松弛现象。
