There is a growing interest for high performance electron cyclotron resonance ion source (ECRIS) working in various environments and dedicated to various purposes. In this article we will present three typical machines using classical FeNdB radial magnets and coils. The first one, called "SuperNanogan II," is a fully permanent magnet machine, copying exactly the ECR4 magnetic structure. Here the purpose consists in producing high currents of high charge state ions on a high voltage platform (up to 250 μAe of 40Ar10+ and 48Ca11+). The second one, called "Super n+," is a very high magnetic field machine dedicated to be used as high performance charge booster for the 1+/n+ ISN/GANIL program. The source is built around a &nullset; 9 cm minimum |B| structure closing a maximum closed magnetic line of 1.8 T, so allowing functioning points from 2.45 to 35 GHz. The third one is a hybrid machine using an existing 4 T superconducting mirror field, where it is possible to place inside a well optimized 1.6 T FeNdB multipole. This machine can be used as a classical 6.4 to 35 GHz ECR ion source or just as an "ECR ion trap" in order to optimize the trapping of hydrogenlike ion for spectroscopic purpose. © 1998 American Institute of Physics.
