Injection scenarios for TNS

PDF Version Also Available for Download.

Description

Neutral beam injection heating is the most technically advanced and experimentally proven form of auxiliary Tokamak heating. In TNS, due to its large size and density, the major problem is a lack of beam penetration. An attempt is made to determine the scope of the problem and outline possible strategies for dealing with it. Some of these strategies are: raise the injection energy, injection vertically into a locally produced minimum in the toroidal magnetic field so that the injected ions are trapped in this well and anti B x nablaB drift into the center of the machine, and using a ... continued below
