在高辐射环境中操作的仪器的开发是基础研究的主要挑战之一。除了空间和核应用，粒子物理实验也需要抗辐射设备。本文的重点是一个新的辐照设施的基础上的医用回旋加速器位于伯尔尼大学医院（Insespital），这是作为一个受控的18 MeV质子源。可调射束电流允许在大的动态范围内（从0.1到1000格拉德/小时）进行剂量率相关表征。可以调整光束，使得用户可以获得期望的照射条件。由于专用的光束监测系统以及用于辐照下的设备的功率控制系统，可以在线操作，因此可以对辐照下的设备进行完整的研究。由于实验室配备了伽马光谱检测器、电流表和瞬态电流技术装置，因此可以对辐照设备进行进一步表征。
The development of instrumentation to be operated in high-radiation environments is one of the main challenges in fundamental research. Besides space and nuclear applications, particle physics experiments also need radiation-hard devices. The focus of this paper is a new irradiation facility based on the medical cyclotron located at the Bern University Hospital (Insespital), which is used as a controlled 18 MeV proton source. The adjustable beam current allows for dose rate dependent characterisation over a large dynamic range, from 0.1 to 1000 Grad per hour. The beam can be tuned so that the user can obtain the desired irradiation conditions. A complete study of the device under irradiation is possible thanks to dedicated beam monitoring systems as well as a power control system for the device under irradiation, which can be operated on-line. Further characterisations of the irradiated devices are possible thanks to a laboratory equipped with gamma spectroscopy detectors, ammeters and transient current technique setups.
