Generation of suprathermal electrons during sawtooth crashes in a tokamak plasma

Ambrogio Fasoli, Timothy Goodman, Igor Klimanov

The acceleration of electrons during a sawtooth crash is demonstrated in various regimes of the TCV tokamak plasma. Simultaneous measurements of electron cyclotron emission from the low field side and from the high field side of the tokamak provide informa ...
