摘要

一种利用光栅扫描技术的光束传输系统被开发出来，它可以用光离子束产生大的辐射场，用于癌症患者的放射治疗。用一束磁刚性为6.9 T-m的氖离子可以产生20cm × 30cm的辐射场。该方法产生的辐射场对波束位置和波束形状的敏感性较弱，但需要更严格的波束溢出要求，以确保均匀的辐射场

Preliminary results of a raster scanning beam delivery system

A beam delivery system using a raster scanning technique has been developed to create large radiation fields with light ion beams for radiation treatment of cancer patients. Radiation fields up to 20 cm by 30 cm have been produced with a beam of Ne ions having a magnetic rigidity of 6.9 T-m. The radiation fields produced by this method appear to be less sensitive to beam position and beam shape than the wobbler dynamic beam delivery system, but require more stringent beam spill requirements to insure uniform radiation fields.<>
