发展了制备厚约10 μg/cm ~ 2长寿命重离子直线加速器剥离剂用碳膜的新方法。采用离子束溅射和碳弧放电技术制备了碳膜。分离剂为KCl和NiCl 2。将碳沉积在加热至约180°C的载玻片上。用3.0 MeV、1 μA的Ne+离子束辐照，溅射法制备的碳箔寿命为5 ~ 55 h，设计、制作了一套大容量（360片以上）的剥离箔更换系统，并成功运行。在本文中，碳箔制备工艺和箔寿命之间的比较，并在附录中的箔更换系统的描述。
New methods for preparing long-lived carbon foils of approximately 10 μg/cm2in thickness for use as strippers in heavy ion linear accelerators have been developed. The carbon foils were made by ion beam sputtering and carbon arc-discharge techniques. Parting agents of KCl and NiCl2were used. Carbon was deposited onto glass slides heated to approximately 180°C. Lifetimes of the carbon foils prepared by ion beam sputtering were determined to be 5 to 55 h when irradiated with 3.0 MeV, 1 μA, Ne+ion beams.A stripper-foil changer system with a large foil capacity (more than 360 foils) was designed, fabricated, and successfully operated. In this paper, comparisons between carbon foil preparation processes and foil lifetimes are made, and a description of the foil changer system is included in the appendix.
