DESCRIPTION:Emelie Nilsson\, CEA-Cadarache\, F\nRunaway electron (RE) form
 ation processes are studied with the gyro-averaged 3D bounce-averaged Fokk
 er-Planck solver LUKE including recently implemented effect of knock-on el
 ectrons\, which can lead to avalanches of relativistic electrons and drama
 tically increase the number of REs for a given level of toroidal electric 
 field. A large fraction of the knock-on electrons are born in the magnetic
  trapping domain in momentum-space owing to their high magnetization\, whi
 ch makes the RE population decrease rapidly with the minor radius. The fat
 e of these trapped-electron runaways is investigated.\nThrough parametric 
 studies of electric field strength\, density\, temperature and magnetic co
 nfiguration\, parameter domains are defined where primary and secondary ge
 neration is dominant. We show that REs can form even in non-disruptive tok
 amak scenarios. Modelling of RE formation in such scenarios from the Tore 
 Supra and COMPASS tokamaks is performed\, using global plasma parameters s
 uch as parallel electric field and plasma equilibrium calculated with the 
 fast integrated modelling code METIS. The METIS/LUKE simulations yield the
  evolution of the electron distribution function and RE population. With t
 his work we aim to contribute to understanding of RE formation processes\,
  and provide information beyond the experimental measurements.
