Recent advances in applied mathematics (Gamba and Rjasanow, JCP 2018) make direct solution of the Boltzmann equation particularly accessible. A newly-developed implementation has been optimized, parallelized, and rigorously benchmarked. Features include general-cross-section large-angle, inelastic, and/or self-collisions. The fully conservative
discrete collision operators are pre-computed and stored on an online database, making time advancement remarkably efficient on local workstations. I will also discuss possible applications for this tool including discharges, reentry blackout, tokamak divertors, runaway electrons, carbon sequestration, and more.
