Summary
In any practical device the magnetic isolation will not be perfect and the walls will also be bombarded by energetic charged particles. Under these conditions wall material may be evaporated into the plasma. The problems of wall erosion are discussed, with particular reference to a reactor based on the pinch effect. Experience gained in experiments with high current discharges in toroidal tubes is included. A theoretical comparison is made of the evaporation from a wide selection of materials under steady and pulsed heat inputs. In general, metals give least evaporation. Sputtering is not a serious cause of erosion in present apparatus but it is shown that it may become more serious under certain conditions. Other considerations affecting the choice of materials such as chemical stability, and neutron and radiation-absorbing properties are briefly discussed. (auth)
