Abstract

LINAC4 H^- source is radio frequency (RF) driven type source. In the RF system, it is required to match the load impedance, which includes H^- source, to that of final amplifier. We model RF plasma inside the H^- source as circuit elements using transformer model so that characteristics of the load impedance become calculable. It has been shown that the modeling based on the transformer model works well to predict the resistance and inductance of the plasma.
