DESIGN OF PROTON MEDICAL ACCELERATOR

该计划的长期目标是发展和 质子加速器的商业化适用于放射治疗 医院或临床环境中的癌症。 为此，加速器 应该有一个能量高达250兆电子伏，必须简单，可靠， 与现有的用于物理应用的加速器相比，价格低廉。 在 此外，如果有足够的创新，它可以具有波束特性， 这将极大地增强和简化其在治疗中的应用 应用程序. 对于具有这些特征的加速器存在概念性想法， 估计建筑成本为100万至150万美元。 I期研究将是 由经验丰富的加速器物理学家和工程师进行。 它将 论证目前的概念构想的可行性，并制定一个 可靠的医用加速器成本估算。 这些结果将是 吸引资本生产原型加速器的基础， 或3个用于医院临床研究的单位（此类兴趣 目前存在）。 第二阶段赠款申请将提交安装， 委托，并开发原型加速器的能力，并 将开发成果移交给临床单位。 第三阶段， 私人支持，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.
