Radioactivity induced by particle acceleration in an unstable laboratory plasma

Acceleration of electrons and ions to walls has been observed during plasma instabilities in a hot electron, electron-cyclotron heated plasma. Radioactivity resulting from ( gamma ,n) reactions with thresholds approximately 10 MeV has demonstrated that electrons are accelerated through several MeV. Radioactivity from 13 N resulting from a (d,n) reaction on 12 C has demonstrated that cold ions are accelerated to at least several hundred keV.
