| titleOfInvention | Plasma magnetic field measuring method and device based on grid modulation phase comparison |
| abstract | The invention belongs to nuclear fusion plasma diagnosis, in particular to a plasma magnetic field measuring method and device based on grid modulation phase comparison. The invention provide a plasma magnetic field measuring method and device with simple steps and low cost by aiming to limitation to the measurement of a poloidal magnetic field. The method specifically comprises the following steps of: (1) obtaining a beam by utilizing a laser emitter; (2) dividing the beam into three groups of interference light paths and simultaneously obtaining a beat signal of a reference path not passing through plasmas, a plasma density beat signal and a plasma poloidal field beat signal; (3) obtaining the electron density of the plasmas by utilizing the phase difference between the density beat signal and the beat signal of the reference path; and (4) obtaining the value of the poloidal field by utilizing the phase difference between the beat signal of the poloidal field and the beat signal of the reference path. By means of the invention, the harms of laser power disturbance and environmental influence brought by traditional amplitude signal measurement are avoided, the measurement is more reliable and the measurement accuracy can be improved. |
