ESTIMATION OF RADIATION LOSS FROM STELLARATORS USING NEOCLASSICAL TRANSPORT THEORY

Abstract

The radiation power loss from a magnetically confined plasma in a
stellarator has been calculated using neoclassical particle and energy fluxes in
an energy balance equation. We could obtain a power loss of about 34% of the
total input power by numerical calculation. This fraction of the power loss has
been found to be in good agreement with the experimentally measured values of
30-40% for our reference machine.
