Abstract

A new �ITER-like� accelerator, which is a scaled down version of the ITER SINGAP (SINgle GAP, SINGle APerture) accelerator, has been built and installed on the Cadarache 1 MV test bed. The objective is to demonstrate reliable D- beam acceleration as close as possible to 1 MeV with a current density j{-}� 200 A/m{2} with the beam optics required for ITER, i.e. a beamlet divergence of </= 7 mrad and beamlet steering within +/- 2 mrad of that specified. High voltage hold off tests have been performed and 940 kV has been held without breakdowns. The first beams up to 850 keV (D{-}, 15 A/m{2}) have been obtained after 4 weeks of experiments and the highest current density that has been obtained so far is 85 A/m{2} (D{-}, 580 keV).
