The high temperature damage about carbon stripper foils has been studied to resolve the short lifetime problem on the high intensity particle accelerators,. This study has been realized hybrid type carbon stripper foils with high durability over 2000K.Results from the experiment are summarized blow.(1) By using the high current de negative ion beam, the very high temperature condition of over 2500K was realized.(2) The damages (growth of distortion, reduced thickness, formation of pin-hole) were studied with high temperature of around 2000K.(3) The irradiation by high current 650keV H-ion beam were executed with stable beam condition during the machine time of 200hours. And the hybrid type carbon stripper foil showed the long lifetime with over 1500K.(4) Comparison of several materials as stripper foil was carried out; (a) Commercially available carbon foil (b) Newly developed KEK hybrid type carbon foil (c) SNS diamond foil (d) Commercially available diamond foil.

已经研究了碳脱衣机箔的高温损害，以解决高强度颗粒加速器上的短寿命问题。这项研究已经实现了杂化型碳脱剥箔，具有高耐用性超过2000k。实验的反应总结了打击。（1）使用高电流DE负离子束，实现了超过2500k的高温条件。（2）损坏（2）损坏（造成损坏，降低的厚度，较高的销量），高度为2000（30次数）。在200小时的机器时间内执行H-ION光束稳定的光束条件。杂化型碳脱衣舞自慰表现出长长的寿命，超过1500K。（4）将几种材料作为脱衣舞箔进行比较； （a）可商购的碳箔（b）新开发的kek混合型碳箔（C）SNS钻石箔（D）市售的钻石箔。
