Effect of electrical ring on ion temperature after magnetoelectric heating

The magnetoelectric heating system had been introduced on a non-symmetric magnetic mirror field ECR plasma apparatus.The effects of radius of electrical ring,axial position of the ring and double electrical ring on the ion temperatures had been studied.The results indicated that a suitable radius of electrical ring could improve ion temperature effectively and the optimal size of electrical ring depended on the cyclotron radius of ions mainly.The axial location of electrical ring was dependent on configuration of magnetic mirror field.It was the most advantageous to improve ion temperatures when electrical ring was set at a region where it had a weaker magnetic field strength in the middle of magnetic mirror field.Double electrical ring could further improve the ion temperature and the ion temperature was increased twice as the one of the single ring after heating.
