Electron Injection by E-Field Drift and its Application in Starting-up Tokamaks at Low Loop Voltage

We propose an innovative method of electron injection by E-filed drift into a plasma device and discuss its application in starting-up tokamak plasmas at low loop voltage. The experimental results obtained from HT-6M Tokamak are also presented. The breakdown loop voltage is obviously reduced and the discharge performance is improved by using the electron injection method. It could be applied to some other types of plasma device.
