在DITE的边界层和偏滤器室中使用了一对不对称的静电双探头。电极结构是这样的，当一个双探头收集向偏滤器目标移动的离子时，另一个探头收集远离偏滤器目标的离子。该探头用于测量流动等离子体的电子温度、密度和马赫数。虽然对马赫数的解释与模型有关，但结果表明，在偏滤器靶面6-10 cm范围内，马赫数约为1~2，而在刮离层，马赫数约为0.3~0.45。
A pair of asymmetric electrostatic double probes has been used in the boundary layer and divertor chamber of DITE. The electrode configuration is such that while one double probe collects ions moving towards the divertor target, the other collects ions moving away from it. The probes are used to measure electron temperature, density and Mach number of the flowing plasma. Although the interpretation of Mach number is model dependent, it is concluded that the Mach number within 6–10 cm from the divertor target ranges from about one to two while in the scrape-off layer it varies from 0.3 to 0.45.
