Abstract :
Seven superconducting focusing magnets have been constructed for vertical gyrotrons devoted to the plasma heating of the tokomak Tore Supra. The performances in magnetic field strength, profile and homogeneity are spread over a large range so as to suit gyrotrons of microwave frequencies extending from 110 GHz to 150 GHz. The cryostats have a low consumption in cryogenic fluids which insure a one week autonomy
