The superconducting ECR ion source SuSI at Michigan State University was designed to operate primarily at 18GHz and has demonstrated very good performance at this frequency especially when coupling two klystrons to the plasma [1]. Following a period of training, SuSI has been able to reach the magnetic field needed for operation in the high-B mode at 24 GHz. SuSI has several interesting features. First the axial magnetic profile is defined using 6 solenoids which provide some flexibility to adjust parameters such as field gradient at the resonance, Bminimum or plasma length. Second with a diameter of only 101mm, SuSI plasma chamber has a nominal volume of about 3.5 l. Therefore, power density in excess of 2kW/l could be reach and lead potentially to new insight on the maximum performance achievable with an ECR. In January 2014, a 10 kW 24 GHz Gyrotron obtained from the Russian company GYCOM was commissioned at MSU on a dummy load and then connected to SuSI. We report here on the first measurements done with SuSI at 24 GHz.
