Pre-study of burn control in Tokamak reactor experiments

Technical Report:

Abstract

Findings from a general study of issues associated with control of burning fusion plasmas are reported, and applications to ITER are given. A number of control variables are discussed. A zerodimensional system has been developed and stability against coupled temperature and density variations are studied. Also space dependent energy balance and transition to thermonuclear burn are analysed as well as maximum obtainable Q-values under subignited operation conditions. Control designs with different input-output strategies are analysed and numerically simulated, and a numerical experiment of system identification is made. Requirements on diagnostics are discussed and areas for further studies are identified. (au) (64 refs.).
