摘要
用７个ＮａＩ（Ｔ１）闪烁探测器组成的阵列观测能量范围在２０—５００ｋｅＶ，来自ＨＴ—７托卡马克等离子体的硬Ｘ射线轫致辐射。实验结果显示，硬Ｘ射线的径向辐射强度分布与低杂波的功率谱和等离子体的密度及磁场强度等放电参数密切相关。通过测量不同放电参数下硬Ｘ射线的径向强度分布，研究低杂波在等离子体中传播和吸收机制。
A seven-channel NaI(T1) detector array installed on HT-7 superconducting tokamak has been used to measure the hard X-ray (20keV <Ehv <500keV) emitted from plasma. The physical mechanism of LHW propagation and absorption in plasma was investigated by the measurement of hard X-ray radial distribution at different discharge parameters.
