摘　　要：电子逃逸是托卡马克等离子体中一种普遍的现象.对逃逸电子的监测是保护装置第一壁材料的基础.托卡马克上等离子体芯部逃逸电子发射的同步辐射是利用红外相机测量,但是红外相机的光路成本高,相机本身也比较昂贵.通过分析KSTAR装置逃逸电子的同步辐射功率谱,研究了逃逸电子同步辐射波长与能量的关系,拟发展新型的逃逸电子诊断系统.In tokamak plasmas, the escape of the electrons is a common phenomenon. It is important to detect the runaway elec- trons in order to protect first wall components of the device. The synchrotron radiation emitted by the runaway electrons in the core of tokamak plasmas can be measured with an infrared camera. But the infrared camera system is expensive. In this paper, the spectrum of synchrotron radiation of the runaway electrons in KSTAR is analyzed. The relationship between the wavelength of syn- chrotron radiation of the runaway electrons and the energy of the runaway electrons is studied. It is found that the visible camera can be used to measure runaway electrons in KSATR.
