Enhanced Electron Confinemet in the Lithium Tokamak Experiment (LTX) Scrape off Layer
POSTER
Abstract
Fluid simulations of the scrape off layer are unable to capture the effects of trapped particles on confinement, which can be important. We use the Gkeyll computational framework, the first successful full-f continuum electromagnetic gyrokinetic code on open field lines to explore particle and heat confinement in the LTX-SOL.Here, we conduct 3 dimensional (1 spatial and 2 velocity dimensions) and 5 dimensional (3 spatial and 2 velocity dimensions) gyrokinetic simulations on open field lines with parameters representative of the LTX scrape off layer to investigate enhanced electron confinement observed in the LTX-SOL.
