托卡马克等离子体旋转速度实时诊断系统

The Real time Diagnostic System of Tokamak Plasma Rotating Velocity

利用一台压电晶体驱动式ＦａｂｒｙＰｅｒｏｔ 干涉仪， 采用偏振分束技术， 设计了一套用于托卡马克等离子体旋转速度测量的实时诊断系统． 实验表明： 该系统具有较高的光谱分辨率， 且成功地避开了谱线Ｄｏｐｐｌｅｒ 展宽对测量精度的限制．

Using a series of polarizers and a Fabry Perot interferometer driven by a piezoelectric crystal, the real time diagnostic system of tokamak plasma rotation velocity is performed. The results show that this system has the higher spectral resolution, and that the limitation of accuracy due to the Doppler broadening is avoided.
