Among the \nmost important questions, we list: scaling of optimal frequency and minimum working pressure \nwith size, applied magnetic field and wall conditions, uniformity of the extracted beam, both within \neach beamlet and from one beamlet to another. \n Together with the full size source (40A, 1MV) elsewhere reported, a 60 kV ion source (9 \nbeamlets of 15 mA each of H-\n) is being developed at Consorzio RFX, for its versatility in \nexperimental campaigns and for training. Magnetic configuration can achieve a minimum |B| trap \nfor the ion source, smoothly merged with the extraction filter. Modular design allows for quick \nsubstitution and upgrading of the parts, mainly the rf coil module (with ferrite magnets) and the \nextraction and postacceleration grids. \nA repeller electrode is added after the postacceleration grid for a better control of the space \ncharge compensation. A 350 mm diameter drift tube allow for insertion of fast emittance scanners \n(FES) and for calorimeters and for adequate pumping. Unlike most experimental sources, the design \naimed at continuous operation, which implies a laborious cooling system. Vacuum chambers are \nbuilt, while industrial validation of source drawing and of construction techniques was completed in \n2010. Construction is well in progress and installation is expected for first month of 2012. \nSeveral accessories were built at INFN-LNL and by industry, and are being tested at LNL \ninstallations: the emittance scanner, the low power matching boxes and. the removable cesium \noven. Experiments with a small radiofrequency plasma generator are also described."@en ; prodottidellaricerca:prodottoDi istituto:CDS037 , modulo:ID2195 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA11833 , unitaDiPersonaleInterno:MATRICOLA1449 , unitaDiPersonaleInterno:MATRICOLA5941 .
