At JAEA as the JApan Domestic Agency (JADA) for ITER, a multi-aperture multi-grid (MAMuG) accelerator has been developed for the ITER neutral beam heating & current drive (NB H&CD) system. A target is H ion beam acceleration of 0.5 A (200 A/m) at 1 MeV for several tens of seconds. In the tests to achieve the 1 MV holding, it was found that the voltage… CONTINUE READING
