Design studies of an aluminum first wall for INTOR

Examination of the plasma performance expected for INTOR indicates that there will probably be high fluxes of charge exchange neutrals to the first wall. The average energies of these neutrals is sufficiently large, in the range of approx. 100 to 300 eV, so that substantial erosion of the first wall by sputtering appears likely. A second concern is the effect of plasma disruptions on the integrity of the INTOR first wall. Every so often in existing Tokamak experimental facilities the plasma suddenly becomes unstable and rapidly dumps its stored energy (thermal and magnetic) onto a portion of the plasma chamber. In addition to the potentialy high-erosion rates (including evaporation) expected for INTOR, but depending on the plasma scenario, there may also be substantial heat flux to the first wall, e.g., approx. 9 (Case I) to 24 (Case II) W/cm/sup 2/. This will come from two sources - radiation and charge exchange neutrals. There will also be internal heat generation by neutron and gamma deposition that must be taken into account since we are considering first wall structures of approx. 3 cm thickness. It is with respect to the above concerns (erosion, evaporation, and high-heat flux) that the aluminum design is addressed.
