称为 BEVALAC 的重粒子复合加速器可以产生放射性核的高能束，作为二次束。使用合适的磁性过滤器和适当的光束光学器件，这些光束可以聚焦到实验区域，而不会产生明显的污染。正确选择放射性核的高能束（那些通过正电子发射衰变的束）可以提供真正独特的机会来评估这些束在将布拉格峰定位在肿瘤体积上的有效性，这在重粒子疗法中是必需的。初步数据表明这些光束在[人类癌症]放射治疗计划验证中的可能用途。
It is possible to produce energetic beams of radioactive nuclei, as secondary beams, from the heavy-particle compound accelerator called BEVALAC. These beams can be focused into experimenal areas without significant contamination using suitable magnetic filters and proper beam-optics. Properly selected high-energy beams of radioactive nuclei (those which decay by positron emission) can provide a truly unique opportunity to evaluate the effectiveness of these beams in localizing the Bragg peak on a tumor volume, necessary in heavy-particle therapy. Preliminary data are presented to demonstrate the possible use of these beams in [human cancer] radiotherapy treatment-planning verification.
