Abstract

Abstract:

Measurement of the LHCD antenna system displacement due to the temperature change is described. The maximal displacement of the LHCD antenna system and the HL-2A vacuum vessel is 3. 47mm , while the displacement of the LHCD antenna system is 0.9mm,at the maximal vacuum vessel temperature 112 ℃. From this displacement , the stress on the LHCD system was calculated. Analyzing the effect on the LHCD system by the baking , the possible means for LHCD transmission system to mitigate it are put forward.

Key words: LHCD, Baking, Thermal stress

摘要：

测量了 HL-2A装置烘烤期间由于温度变化引起的LHCD天线系统位移, 得到了装置真空室达到最高的温升112℃时的真空室和天线的总的最大位移为3.47mm , 其中天线系统自身的位移为0. 9mm。根据这个位移, 定性地算出 LHCD系统中可能产生的应力。据此, 分析了烘烤对LHCD系统带来的影响以及提出了可能采取的缓解措施。
