摘要：

As an alternative for ITER NBI a RF source is being developed at IPP, Garching. This paper reports the first results with deuterium extracted from a restricted extraction area and accelerated to about 22 KeV. A current density of 150 A/m(2) (calorimetric) of D- ions has been reached so far in a Cs-seeded discharge with an electron/ion ration of <= 1. The effect of the magnetic filter field on the yield and the electron suppression and possible limitations/improvements are discussed. The neutron production rate is about a factor 40 lower than expected from positive ions. Possible reasons for this are discussed. (c) 2005 Elsevier B.V. All rights reserved.
