Query: SOL-KiT -- fully implicit code for kinetic simulation of parallel
  electron transport in the tokamak Scrape-Off Layer   Here we present a new code for modelling electron kinetics in the tokamak
Scrape-Off Layer (SOL). SOL-KiT (Scrape-Off Layer Kinetic Transport) is a fully
implicit 1D code with kinetic (or fluid) electrons, fluid (or stationary) ions,
and diffusive neutrals. The code is designed for fundamental exploration of
non-local physics in the SOL and utilizes an arbitrary degree Legendre
polynomial decomposition of the electron distribution function, treating both
electron-ion and electron-atom collisions. We present a novel method for
ensuring particle and energy conservation in inelastic and superelastic
collisions, as well as the first full treatment of the logical boundary
condition in the Legendre polynomial formalism. To our knowledge, SOL-KiT is
the first fully implicit arbitrary degree harmonic kinetic code, offering a
conservative and self-consistent approach to fluid-kinetic comparison with its
integrated fluid electron mode. In this paper we give the model equations and
their discretizations, as well as showing the results of a number of
verification/benchmarking simulations.
