In the frame of the Tulip Project, an application for accelerator technology to radiation therapy, supported by a CERN Knowledge Technology Fund, the design, manufacture and test of a compact, fast trimmable iron cobalt (FeCo) accelerator dipole magnet prototype has been performed and completed at CERN. The aim of this project is to illustrate the benefits of a FeCo magnet for medical gantries in which weight and size are critical. The prototype is a 250 mm long dipole providing a central field of up to 1.8 T, the field can be trimmed in the percent range at frequencies of up to 200 Hz. The experimental results clearly demonstrate that FeCo magnets can be interesting alternatives for medical gantries because of their linear behaviour up to high fields and their compact nature.

开发用于医疗门架的紧凑且可快速修整的FeCo磁体

在Tulip项目的框架内，在CERN知识技术基金的支持下，将加速器技术应用于放射治疗，已经完成了紧凑，可快速修整的钴铁（FeCo）加速器偶极磁体原型的设计，制造和测试，并且在CERN完成。该项目的目的是说明重量和尺寸至关重要的医用门架式FeCo磁体的好处。原型是一个250毫米长的偶极子，可提供高达1.8 T的中心磁场，可以在高达200 Hz的频率的百分比范围内对磁场进行微调。实验结果清楚地表明，FeCo磁体可以成为医疗门架的有趣替代品，因为它们在高磁场下的线性行为及其紧凑的性质。
