Heat fluxes and energy balance in the FTU machine
Thermal loads on the FTU limiter are routinely measured and energy losses via conduction/convection are inferred. A small fraction of the input power (4 to 8 %) has been measured from temperature increases in the limiter mushrooms. Numerical evaluation and comparison with thermocouples located at different radial positions in the SOL suggest a long energy decay length. The power loads inferred from the estimated decay length in the actual geometry of the limiter and first wall lead to a global energy balance which is close to being satisfactory.
