Description
RAON fully superconducting ECRIS which plasma chamber volume of 10 liters is adapted and uses a 28 GHz MW power as a main power source and an 18 GHz MW power as a secondary power source. We characterized our ion source at a relatively low magnetic field just with an 18 GHz MW power. A reference O$^{7+}$ beam was monitored with the experimental parameters such as MW power, vacuum pressure, and magnetic field profile. Under some conditions, the beam current showed unstable behavior due to a plasma instability. We verified the reason of that instability and verify the characteristics of our ECRIS.
