摘　　要：用新研制的五通道碘化汞 ( Hg I2 )半导体探测器阵列分别观测了在欧姆加热、弹丸注入及离子回旋共振加热 ( ICRH)条件下 ,HL- 1M等离子体中的超热电子引起的能量在 10～ 15 0 ke V范围内的 X射线辐射强度的时空变化 ,及超热电子辐射的 X射线能谱。结果显示 ,在 ICRH期间 ,等离子体边缘的 X辐射增强 ,超热电子的温度大约为 30 ke V,ICRH的能量沉积在等离子体边缘。Using a new array of five iodine mercury (HgI 2) semi conductor detectors,the radiation flux and the energy spectra of X ray in the range of 10～150keV are measured under the condition of ohmic heating,pellet injection and ion cyclotron resonance heating (ICRH) respectively.The experiment results show that the flux of X ray radiation increases near the edge of plasma during ICRH,and the temperature of suprathermal electrons is about 30keV,the energy of ICRH is deposited in area near the edge of plasma in the HL 1M tokamak.
