THE BUNDLE DIVERTOR - A REVIEW OF EXPERIMENTAL RESULTS
This paper is a review of the experimental results obtained with a tokamak, DITE, operated with a bundle divertor. Experiments to determine the magnetic aperture, exhaust and screening properties of the divertor are described. The results are compared with the predictions of various models. A comparison of the plasma parameters produced with and without the divertor is presented. The differences are discussed in terms of the exhaust and screening properties, with the aid of a global model of impurity production. Neutral hydrogen atom injection has been used to heat the plasma; results are presented, together with a discussion of the effect of the magnetic field ripple, produced by the divertor, on confinement. Gross instability characteristics of plasma produced with the divertor are discussed, together with their effect on the divertor properties. Possible explanations for different operational characteristics are considered. Finally, a comparison between the results obtained with the bundle divertor, and poloidal divertors, is presented.
