DESIGN OF PROTON MEDICAL ACCELERATOR

这项计划的长远目标是发展和 适用于放射治疗的质子加速器的商业化 医院或临床环境中的癌症。为此，加速器 应具有高达250兆伏的能量，并且必须简单、可靠和 与现有的用于物理应用的加速器相比，价格低廉。在……里面 此外，如果有足够的创新，它可以具有光束特性 这将大大增强和简化其在治疗中的使用 申请。 具有这些特性的加速器存在概念上的想法 预计建筑成本为100万至150万美元。第一阶段的研究将是 由经验丰富的加速器物理学家和工程师进行。它会 论证当前概念想法的可行性，并开发一个 医疗加速器的可靠成本估算。这些结果将是 吸引资本生产原型加速器的基础和2 或3个拟在医院进行临床研究的单位(此类兴趣 目前存在)。将提交第二阶段拨款请求以进行安装， 委托，并开发原型加速器的能力，并 将发展成果转移到临床单位。第三阶段， 私人支持的，将提供商业单位。

The long range goal of this program is the development and commercialization of proton accelerators suitable for radiation therapy of cancer in hospital or clinical settings. For this purpose the accelerator should have an energy up to 250 Mev, and must be simple, reliable, and inexpensive compared to existing accelerators for physics applications. In addition, with sufficient innovation, it could have beam characteristics which would greatly enhance and simplify its use for the therapy application. Conceptual ideas exist for accelerators with these characteristics and with an estimated construction cost of $1M to $1.5M. The Phase I study would be carried out by experienced accelerator physicists and engineers. It would demonstrate the feasibility of the present conceptual ideas and develop a reliable cost estimate for the medical accelerator. These results would be the basis for attracting capital to produce a prototype accelerator and 2 or 3 units intended for clinical studies in hospitals (such interest presently exists). A Phase II grant request will be submitted to install, commission, and develop the capability of the prototype accelerator, and to transfer the development results to the clinical units. Phase III, supported privately, would make available commercial units.
