Abstract :
The successful conversion of the JET, (Joint European Torus) neutral injectors to operate in helium has further enhanced the usefulness of neutral injection on JET. Each of the two injectors can now operate in H, D, 3He, or 4He. The operation of a long-pulse 3He NBI (neutral-beam injector) has been demonstrated for the first time. Up to 7 MW of 4He and 13 MW of 3He neutral beam power have been injected into JET. The beams have been operated at energies up to 150 keV, with pulse lengths up to 7 s
