在大型螺旋装置（LHD）实验中，用钇铝石榴石（YAG）激光汤姆森散射诊断观察到电子温度（T(e)）大于15 keV。由于LHD汤姆逊散射系统针对50 eV≤T(e)≤10 keV的温度区域进行了优化，在超过10 keV的较高T(e)区域数据质量变差。为了在LHD高T(e)实验中准确测定T(e)，我们尝试通过同时发射三束激光来增加激光脉冲能量。该技术使我们能够减少测量T(e)的不确定度。还测试了另一种信号积累方法。此外，我们估计了高能电子对LHD汤姆逊散射系统得到的T(e)的影响。
In Large Helical Device (LHD) experiments, an electron temperature (T(e)) more than 15 keV has been observed by the yttrium-aluminum-garnet (YAG) laser Thomson scattering diagnostic. Since the LHD Thomson scattering system has been optimized for the temperature region, 50 eV≤T(e)≤10 keV, the data quality becomes worse in the higher T(e) region exceeding 10 keV. In order to accurately determine T(e) in the LHD high-T(e) experiments, we tried to increase the laser pulse energy by simultaneously firing three lasers. The technique enables us to decrease the uncertainties in the measured T(e). Another signal accumulation method was also tested. In addition, we estimated the influence of high-energy electrons on T(e) obtained by the LHD Thomson scattering system.
