Non-local transport in Radiation-Hydrodynamics codes for ICF by efficient coupling to an external Vlasov-Fokker-Planck code
Abetharan Antony, Robert Kingham, Stefan Mijin +1
Accurately incorporating non-local transport into radiation-hydrodynamics codes, and indeed any fluid system, has long been elusive. To date, a simplified and accurate theory that…
The impact of non-local parallel electron transport on plasma-impurity reaction rates in tokamak scrape-off layer plasmas
Dominic Power, Stefan Mijin, Kevin Verhaegh +2
Plasma-impurity reaction rates are a crucial part of modelling tokamak scrape-off layer (SOL) plasmas. To avoid calculating the full set of rates for the large number of important…
