Abstract

Each GA ECH launcher mirrors is used to transmit 800 kW of power to the plasma. Until 2000, the pulse length for use of these mirrors was limited to 2 s due to temperatures of the mirrors resulting from 1) a high ratcheted bulk temperature and 2) a large increase in temperature of the mirror during the pulse. A new design was proposed and implemented which has extended the capability of the mirror to 10 s with passive cooling. The important features of the new design are 1) increase in the passive heat transfer rate during cooling and 2) a modified shape of the mirror. The analysis shows that, the new mirrors can be used for 10 s pulses. The new mirrors have been installed in DIII-D, they have been used for up to 2 s pulses.

GA ECH发射镜长脉冲热设计

每个GA ECH发射镜用于向等离子体传输800千瓦的功率。直到2000年，使用这些反射镜的脉冲长度被限制在2秒，这是由于反射镜的温度造成的:(1)高棘轮体温度;(2)在脉冲期间反射镜的温度大幅升高。提出并实施了一种新的设计方案，该方案将反射镜的被动冷却能力扩展到10秒。新设计的重要特点是1)增加了冷却过程中的被动传热率，2)改进了反射镜的形状。分析表明，新型反射镜可用于10s脉冲。新的反射镜已安装在DIII-D中，它们已用于高达2秒的脉冲。

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.
