Title:     Development of neutral beam injection for ITER (International Thermonuclear Experimental Reactor)

Abstract: Currently negotiations are entering their final phase of site selection for the ITER project. This project will be the first step towards the commercial production of electricity by nuclear fusion. It is planned that like all successful fusion machines today ITER will rely heavily on NBI (Neutral Beam Injection) for heating, current drive and fueling purposes. The NBI system for ITER is planned around a pair of 16 MW D- beam lines. Each beam will be driven by a 1 MeV 40 A ion source. The question of type of source remains however; IPP has been developing an RF source as an alternative to the reference source (arc driven) for the past several years. The main advantages of the RF source are in maintenance and cost savings, and an intensive series of investigations over the last two years has now closed the performance gap between the two types of sources. At the core of the ITER NBI are two poorly understood processes: the creation and extraction of negative hydrogen ions. This talk is intended to inform the audience of the challenges that still remain in the development of the ITER source as well as to introduce non-specialists to this alternate use and scale of the familiar H- ion sources and beam lines that are the heart of the TRIUMF accelerator complex.

Stimulants available 15 minutes before the talk.
