ELECTRON STRIPPER FOILS AND PARTICLE ACCELERATORS HAVING THE SAME

The invention provides a particle accelerator configured to direct a particle beam of charged particles along a designated path. The particle accelerator also includes an extraction device positioneddownstream from the particle accelerator. The extraction device includes a stripper foil and a foil holder that holds the stripper foil. The foil holder is configured to position the stripper foil across the designated path of the particle beam such that the particle beam is incident thereon. The stripper foil is configured to remove electrons from the charged particles, wherein the stripper foilincludes a backing layer and a conductive layer stacked with respect to one another. The backing layer includes synthetic diamond. 本发明提供了种粒子加速器，所述粒子加速器产生并沿指定路径引导带电粒子的粒子束。所述粒子加速器包括引出装置。所述引出装置包括剥离箔和保持所述剥离箔的箔保持件。所述箔保持件将所述剥离箔定位在所述粒子束的指定路径上，使得粒子束入射到其上。所述剥离箔从带电粒子去除电子，其中，所述剥离箔包括相对于彼此堆叠的背衬层和传导层。所述背衬层包括合成金刚石。
