This proposal is for the purchase of a custom-made ultra-high vacuum sample-transport system, or “vacuum suitcase”. This device will allow easy, reliable, and secure transfer between the key experimental facilities that propel the quantum material effort at UBC, where surfaces and heterostructures of these novel materials are prepared with atomic precision. In addition to the Quantum Materials and Devices Foundry (QMDF) where films and heterostructures are grown by Molecular Beam Epitaxy (MBE), this include extremely surface sensitive techniques to study their momentum- and atomically-resolved electronic structure, such as Angle-Resolved Photoemission Spectroscopy (ARPES) in Damascelli’s Quantum Materials Laboratory (QML), Scanning Tunneling Spectroscopy in Bonn and Burke’s LAIR facility, or Sawatzky’s newly funded Quantum Materials Electron Microscopy Centre. A key role will be played also by the UBC beamlines at the Canadian Light Source (CLS), i.e. the Quantum Materials Spectroscopic Center for spin-ARPES and the Resonant Elastic and Inelastic X-Ray Spectroscopy beamline.

该建议是购买一个定制的超高真空样品运输系统，或“真空手提箱”。该设备将允许在关键实验设施之间进行轻松、可靠和安全的传输，推动UBC的量子材料工作，这些新型材料的表面和异质结构以原子精度进行制备。除了通过分子束外延（MBE）生长薄膜和异质结构的量子材料和器件铸造厂（QMDF）外，还包括用于研究其动量和原子分辨电子结构的极其表面敏感的技术，例如角分辨光发射光谱（ARPES）达马塞利的量子材料实验室（QML）、波恩的扫描隧道光谱和伯克的LAIR设施，或萨瓦茨基新资助的量子材料电子显微镜中心。加拿大光源（CLS）的UBC光束线也将发挥关键作用，即量子材料光谱中心的自旋ARPES和共振弹性和非弹性X射线光谱光束线。
