The first 18 GHz ECR plasma in an ion source prototype with a magnetic structure using high field magnets techniques was performed in 2012. The particularity of such a prototype is the establishing of a topologically closed ECR zone in a cusp configuration. During the current increase to get a closed 60 GHz zone, a failure appeared at 21000 A in one helix among the four. After the modification of the cooling circuit, the prototype was able to accept up to 26000 A allowing high frequency experiments. In the same time, a 60 GHz - 300 kW pulsed gyrotron has been successfully built and installed in Grenoble by IAP-RAS and Gycom company. The first 60 GHz ECR plasma has been produced in April 2014, the first pulsed beams have been extracted and analyzed. The experimental results obtained will be presented along with the perspectives of such developments.

GANIL has been producing many stable beams for nearly 30 years. Constant progress have been obtained in terms of intensity, stability and reliability. The presentation highlights recent results obtained for 50Ti beam production from an organo-metallic compound using the MIVOC (Metallic Ions from Volatile Compounds) method with the ECR4 ion source. The synthesis of this compound has been studied and realized by the IPHC-Strasbourg team from isotopically enriched titanium metal. Preliminary tests using natural titanocene were performed to validate the production method in terms of beam intensity, stability and reliability. Results obtained allowed us to program a physics experiment in September 2013. A 50Ti10+ beam was maintained stable for 300 h with a mean intensity of 20 μA. Q/A=1/3 ion source of SPIRAL 2 facility, whom commissioning will be led by end of 2014, is Phoenix V2 ion source which has been developed by LPSC-Grenoble. Results obtained for nickel (58Ni19+) and calcium (40Ca16+) in collaboration with LPSC Grenoble will be presented in this report.
