Abstract
All large Tokamaks ( I{sub p} > 1 MA and B{sub t} > 3 T) have reported observations of high levels of runaway electrons during major disruptions. Typical values are: Electron energy: 30 to 60 MeV; Equivalent current: up to 2 MA; Total energy: over 1 MJ. Extrapolation to future Tokamaks is difficult, but as all these values tend to increase strongly with the plasma current, Runaway electron suppression will probably present a real challenge for the next step devices. These electrons strike the first wall components on small areas, thus producing very high thermal loads: values up to 10 kJ/cm{sup 2} have been already observed on TORE-SUPRA and JET. The possibility to avoid (or limit) the consequences of this phenomenon is investigated.
