The microwave absorption of ceramic-cup microwave ion source

摘要

An experiment system of ceramic-cup microwave ion source has been built here. Its microwave absorption efficiency as a function of the magnetic field and the pressure is presented. When the microwave incident power is 300-500W the microwave absorption efficiencies are more than 90/100 if the system is optimized and the magnetic field at the microwave window is - 0.095T.
