Abstract:

To explore the influence of the RF ion source driver coil electric parameters on the RF discharge, the physical analysis of RF ion source plasma excitation was carried out, and the relationship between the frequency selection of RF power source and coil discharge current, coil voltage and discharge pressure was studied. The main parameters of RF ion source driver was designed, the RF ion source driver device is developed. The last device obtained successfully hydrogen plasma RF discharge. The experimental results and theoretical calculation results accord with well.
