Abstract

A new technique for studying high heat flux interactions with plasma facing components is presented. The beam from a continuous wave 300 W neodymium laser was focussed to 80 W/mm/sup 2/ and scanned at high speed over the surface of carbon tiles. These tiles were previously used in the TFTR inner limiter and have a surface layer of amorphous hydrogenated carbon that was codeposited during plasma operations. Laser scanning released up to 84% of the codeposited tritium. The temperature rise of the codeposit on the tiles was significantly higher than that of the manufactured material. In one experiment, the codeposit surface temperature rose to 1,770/spl deg/C while for the same conditions, the manufactured surface increased to only 1,080/spl deg/C. The peak temperature did not follow the usual square-root dependence on heat pulse duration.

高热流相互作用及扫描激光去除等离子体表面元件中的氚

提出了一种研究等离子体表面元件与高热流相互作用的新技术。用300 W的连续波钕激光器将光束聚焦到80 W/mm/sup /，在碳瓦表面进行高速扫描。这些瓦片以前用于TFTR内限制器，表面有一层在等离子体操作期间共沉积的无定形氢化碳。激光扫描释放了高达84%的共沉积氚。砖上共沉积的温升明显高于制造材料的温升。在一个实验中，共沉积表面温度上升到1770 /spl℃，而在相同的条件下，制造表面温度仅上升到1080 /spl℃。峰值温度不遵循通常的对热脉冲持续时间的平方根依赖。

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
