Modeling TLE’s and TGF’s

Modeling TLE’s and TGF’s workshop at the Lorentz Center@Snellius, Oct. 20 – 24, 2014

Topics of this workshop are methods and models that reach from microscopics to macroscopics:

Proper cross-sections from the discharge regime (0.03 eV to 1 keV) to higher energies (here up to 100 MeV), based on research of other communities (CERN, extended air showers, nuclear and radiation medicine, …)
Deriving fluid models from these cross-sections
Efficient calculations with MC and fluid models
Proper initial conditions for simulating discharges in particular regions of the atmosphere, which mechanisms to include where
Including space charge effects in 2D and 3D computing, solving the Poisson equation
Larger scale models of DBM-type
Longer time dynamics: discharge chemistry, discharge heating, coupling of plasma and gas flow
