Abstract
To demonstrate ITER NBI (1Â MV, 40Â A) relevant beam optics in the Cadarache 1Â MV, 100Â mA test bed, a new Dâ beam source system has been put into operation. The system retains a maximum of the ITER SINGAP key parameters, e.g. the perveance matched Dâ current density at 1Â MeV is 20Â mA/cm2. The accelerator parameters are identical to the ITER SINGAP design, aiming at a near parallel 1Â MeV beam of 5Â mrad divergence. The design is aimed at also demonstrating SINGAP “on to off-axis” beam steering by a simple transverse displacement of the post-acceleration electrode. First beams up to 850Â keV have been obtained after only 4 weeks of commissioning.
