A main purpose of this project has been completed to make the apparatus for the pulsed laser plasma ablation and to measure the lifetime of the thick carbon stripper foils made by using it.We have also measured the evaporation rate and the thickness uniformity, and found the heating method to prevent from curling of foil in peeling off from a substrate.The lifetime measurement of the thick foil with 100-250mug/cm^2 have been carried out by using 3.2MeV,1-3muA,^<20>Ne^+ beam with 3.5mmphi spot from Van dee Graff Accelerator at Tokyo Institute Technology. The lifetime in average were obtained to be 80mC/cm^2 which corresponds to 6 times longer than that of commercially available foil.

本项目的主要目的是研制脉冲激光等离子体烧蚀装置，并对用该装置制作的厚碳剥离薄膜进行寿命测量。测量了薄膜的蒸发速率和厚度的均匀性，找到了防止薄膜剥落时卷曲的加热方法。用东京工业大学Van Dee Graff加速器的3.2 MeV，1-3muA，^&lt；20&gt；Ne；+束流进行了100-250mug/cm~2厚薄膜的寿命测量。平均寿命为80mC/cm~2，相当于市售铝箔的6倍。
