	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. * L.T. Sun, J. Brandon, D.G. Cole, M. Doleans, G. Machicoane, D. Morris, T. Ropponen, L. Tobos., ECRIS 2010 (MOCOAK02)

	Since October 2009 more than 2000 patients were treated at HIT. In a 24/7 operation scheme two 14.5 GHz electron cyclotron resonance ion sources are routinely used to produce protons and carbon ions. The integration of a third ion source into the production facility was done in summer 2013 to produce a helium beam. This paper will give a status report of the ion source operating experience and statistics and will summarize the enhancement activities, which were undertaken at an in-house ion source testbench.

THOMMH01	Boron Ion Beam Production with the Supernanogan ECR Ion Source for the CERN BIO-LEIR Facility	ion, ion-source, ECR, plasma	132

	To deliver B³⁺ ions for medical research the compounds decaborane and m-carborane were tested using the metal ions from volatile compounds (MIVOC) method with the Supernanogan 14.5 GHz ECR ion source. Using decaborane the source delivered less than 10 uA intensity of B³⁺ and after operation large deposits of material were found inside the source. Using m-carborane 50 uA of B³⁺ were delivered without support gas. For both compounds Helium and Oxygen support gasses were also tested, and the effects of different source tuning parameters are discussed. The average consumption of m-Carborane was 0.1 mg/uAh over all operation.
