Runaway electron generation in plasmas is a phenomenon that is rich in basic physics and has also great practical importance. It is a candidate mechanism for electron acceleration in solar flares, it is frequently observed in electric discharges associated with thunderstorms, and it occurs also in tokamak disruptions, when the
plasma current is forced to change too quickly and a large electric field is induced. In tokamaks, runaways may damage plasma facing components due to their highly localized energy deposition. The potential for detrimental effects increases with plasma current. Therefore, understanding the processes that may eliminate runaway beam
formation is very important for future reactor-scale tokamaks with high currents, such as ITER.
The aim of the meeting is to make progress in the modelling of runaway electron dynamics, with a particular focus to runaways in tokamak disruptions. This is the 8th edition of the Runaway Electron Modelling (REM) workshop and is open for **all interested researchers**. The workshop hosts also the meeting of the EUROfusion "Theory, Simulation, Validation and Verification" project "Modelling of electron runaway in tokamak disruptions in the presence of Massive Material Injection".
