POWER DENSITY ABSORPTION PROFILE IN TOKAMAK PLASMA WITH ICRH

摘要

The problem of radial profile of power density absorption in multispecies plasma (D-T plasma) by Ion Cyclotron Resonance Heating (ICRH) in tokamak fusion device is analyzed. The profile of power absorption is of great importance both for the heating efficiency and the transport. This profile is actually not a simple Gaussian, as is sometimes approximated, but a more complex function. Analytic expressions are proposed here for Tritium and Deuterium for a well description of the power deposition profile.
