HEAT FLUXES AND ENERGY BALANCE IN FT LIMITERS
The main poloidal limiter used in FT during 1983 consists of 38 mushroom-shaped pieces tightened onto a supporting structure. All items are made of stainless steel (AISI 316). Measurement of weight losses and also observation of damage have been carried out. An e-folding length lambda-E < 1 cm was estimated. A global energy balance gives a maximum total power on the limiter of about 300 kW. Weight loss measurements on the fraction of the limiter involved in disruption reveal that only a fraction of the thermal energy of the plasma is absorbed by the material suggesting the presence of some self-protecting mechanisms around the limiter.
