在快速点火研究中，激光产生的超热电子发散是一个严重的问题。使用类金刚石(DLC)锥体是解决这一问题的现实解决方案之一。然而，要制作一个独立的DLC锥体是困难的，因为它需要一个很厚的DLC层。在本文中，我们报告了厚类金刚石层制备条件的调查结果。采用等离子体基离子注入沉积系统制备了类金刚石薄膜。以乙炔气体或甲苯蒸汽为源。通过对多种沉积条件的试验，发现低气压、低射频功率的沉积条件更适合厚膜DLC的沉积。用近边X射线吸收精细结构(NEXAFS)和弹性反冲检测分析(ERDA)对制备的DLC层的性能进行了测试。结果表明，这些DLC层具有典型的氢化非晶态DLC特性。基于这些结果，我们成功地制作了独立的类金刚石锥体。
In fast ignition research, a divergence of laser-generated hot electrons is a serious problem. Using diamond like carbon (DLC) cones is one of the realistic solutions to this problem. However, it is difficult to make a stand-alone DLC cone because it needs a thick DLC layer. In this paper, we report survey findings of preparation conditions for a thick DLC layer. DLC layers were prepared by using plasma–based ion implantation and deposition system. Acetylene gas or toluene vapor was used as a source. After trials of many deposition conditions, it is found that low gas pressure and low RF power condition is suitable for a thick DLC deposition. Properties of the made DLC layers were measured by near edge X-ray absorption fine structures (NEXAFS) and elastic recoil detection analysis (ERDA). It is found that these DLC layers have typical hydrogenated amorphous DLC properties. Based on these results, we succeeded in making stand-alone DLC cones.
