A 2-D PIC/MC/Vlasov method for electrostatic fusion discharges

Abstract

A kinetic plasma simulation is presented for an Electrostatic Fusion device operating at units and tens of mTorr. The simulation included particle-in-cell (PIC), Monte Carlo (MC) and Vlasov equation components. The simulation was designed to model these devices including previously neglected atomic physics interactions and to subsequently generate experimental Doppler spectra for verification. The large variation in plasma conditions in the different regions of these devices required a number of different mitigating techniques. A novel kinetic treatment of cold electrons is presented.
