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.
