The European DEMO is a pulsed device with pulse length of 2 hours. functions devoted to the heating and current drive system are: plasma breakdown, ramp-up flat-top where fusion reactions occur, control during phase, finally ramp-down. EU-DEMO project was in Pre-Concept Design Phase 2014-2020, meaning that some cases, design values precise requirements from physics point view were not yet frozen. A total 130 MW considered for all phases plasma: flat top, 30 required neoclassical tearing...
Abstract In this paper we look at the technological constraints of neutral beam injection (NBI) systems and compare them with functional requirements that NBI has in various envisaged plasma scenarios for tokamak fusion reactors DEMO power plant (FPP) class. We show particular there is an intermediate energy range which beamlines are unattractive because size. Furthermore, consider only ion heating during ramp-up heat-to-burn phase use energies 100 to 200 keV, could be produced from positive...
Abstract Plasma neutralisers promise increased neutralisation efficiency of negative ion beams in neutral beam injection (NBI) beamlines compared with gas neutralisers. It has been suggested that, the presence an electron-confining magnetic cusp field along all neutraliser walls, itself could ionise sufficiently to take advantage this effect, avoiding added complexity external power coupling neutraliser. These predictions come from a zero-dimensional model by Surrey and Holmes (2013 AIP...
Abstract The large ion source of ITER’s neutral beam injection (NBI) systems (0.9 m×1.9 m) with 1280 apertures has to deliver 57 A D - for 3600 s (286 A/m 2 ) and 66 H 1000 (329 ). RF test facilities ELISE BUG at IPP are aimed demonstrate the parameters, homogeneity beams (up 1 m×1 perform optic studies. While ITER parameters could be demonstrated in hydrogen, achievement deuterium long pulses is still pending due fraction co-extracted electrons, their temporal dynamics, inhomogeneity...
