High power negative ion beam development for heating and current drive in fusion plasmas
Intense D(-) ion beams of 2.2 A, transmitted on a calorimetric target at 6.4 m from the source and with energies up to 100 keV in multi-second pulses, have been obtained at Cadarache in a joint Euratom-CEA JAERI experiment. The plasma generator was operated with caesium. At the exit of the beam neutralising gas cell, the neutral, positive and negative beam components were separated electrostatically and measured calorimetrically for different gas target thicknesses. Energy recovery experiments were conducted for the first time with negative ions. The residual negative ion power was recovered with an efficiency as good as 81 % with 102 keV, 1.2 A D(-) beams.
