主 题:ECR ion sources plasma microwaves ion beams superconducting magnets
摘 要:Since the end of’70s the Electron Cyclotron Resonance ion sources(ECRIS)allowed to increase both the energy and intensity of the beams available from different types of accelerators;perspectives for the future are still *** is commonly agreed that only some ECRIS parameters have been fully exploited, whether some others are still not efficiently used,or not *** developments in the last 20 years have followed the so called Standard Model and the availability of higher frequency generators and higher field magnets have permitted relevant increase;the use of Nb_3Sn may extend the *** availability of new schemes of microwave coupling to plasma is promising,and the focusing of the electromagnetic wave towards the chamber axis may improve the density of warm electron *** paper will also describe some critical point of the 3^(rd) generation ECRIS(including technological troubles and limits)and the scenario for future 4^(th) generation ECRIS,operating at f=56—75GHz,to be built in 2010s.
