First Plasma achieved on the prototype

The development of the internal RF Ion Source for Cyclotrons concept and development of a first prototype of this ion source is described. The document presents also the first results of the prototype installed on th eupdated Ion Source Test Bench (IST) in CIEMAT, including visual check that the plasma is produced and the conditions for the start and stop of the plasma. Further work will include spectral analysis of the plasma, and extraction current measurements,
