A new application of retarding field analyzer for the electron and ion temperature measurement (named eiRFA) has been realized on the J-TEXT tokamak. A novel bias arrangement is adopted for the eiRFA to implement the simultaneous measurement of the electron and ion temperatures in the scrape-off layer, as well as the floating potential, plasma space potential, and sheath potential drop coefficient. It shows that the temperatures measured by eiRFA are reasonable and the plasma space potential obtained by two means is in good self-consistent. Moreover, the calculation of electron temperature can be modified using the eiRFA.
一种用于测量电子和离子温度的减速场分析仪的新应用（称为eiRFA）已在J-TEXT托卡马克装置上实现。eiRFA采用了一种新颖的偏置布置，以实现对刮削层中电子和离子温度的同时测量，以及对浮动电位、等离子体空间电位和鞘层电位降系数的测量。结果表明，eiRFA测量的温度是合理的，通过两种方法获得的等离子体空间电位具有良好的自洽性。此外，利用eiRFA可以改进电子温度的计算。
