利用电子回旋波克服了ECR等离子体产生中的密度限制。通过平行注入频率为2.45GHz的圆极化微波，获得了密度为3×10 13 cm-3的等离子体，其密度比普通模截止密度高40 0倍。结果表明，等离子体产生于入射位置和ECR点之间的高场侧区域，这是由于高能电子的产生和多普勒频移回旋共振的结果。
The density limit in ECR plasma production is overcome using electron cyclotron waves. The plasma of 3×10 13 cm -3 density is achieved by parallel injection of circularly polarized microwaves with a frequency 2.45 GHz, corresponding to a 400 times higher density than ordinary mode cutoff. It is found that the plasma is produced in the high field side region between the incident position and the ECR point, and this is due to the generation of high energy electrons and the Doppler-shifted cyclotron resonance.
