PHYSICS DESIGN OF THE DEFLECTION MAGNETS OF THE JET NEUTRAL BEAM INJECTOR
This paper presents the ion optical calculations for the deflection magnets of the JET neutral injection system. The large amount of ion power to be handled (26 MW) requires more accurate calculations than before. These include 3-D magnetic field computations, ray- tracing and emittance calculations, the latter applied to a multiple aperture ion beam. The resulting power deposition profiles for the full energy ions (80 keV hydrogen, 160 keV deuterium) and for the fractional energy ions are reported.
