Abstract
Three aspects of tokamak edge physics are addressed. Role of radial
electric field and poloidal rotation at the L-H transition is investigated
with the Monte Carlo code ASCOT. Ripple ions and their use in measuring edge
electric field are studied. Generation of fast electrons and hot spots in the
lower hybrid grill region by the RF electric field is investigated with
particle-in-cell simulations.
