Electron-beam extraction system for the Frankfurt 14 GHz electron cyclotron resonance ion source
A new concept to assist in the extraction of ion beams from an electron cyclotron resonance ion source ~ECRIS! by the injection of an electron beam from the extraction side into the ion-source plasma is proposed. In this article, the construction of a test setup is described and first results of experiments with this setup at the 14 GHz ECRIS of the Frankfurt ECRIS-~ve!RFQ facility are reported...
متن کاملConceptual Design of a Sputter-type Negative Ion Source Based on Electron Cyclotron Resonance Plasma Heating
A design for a negative ion source based on electron cyclotron resonance plasma heating and ionization by surface sputtering is presented. The plasma chamber of the source is an rf-cavity designed for TE111 eigenmode at 2.45 GHz. The desired mode is excited with a loop antenna. The ionization process takes place on a cesiated surface of a biased converter electrode (cathode). The ion beam is fu...
