Abstract Text:
Modeling the plasma-wall recombination zone in a tokamak where the atomic and molecular processes are essential in determining the power flow requires a coupled atomic and molecular collisional radiative (CR) modeling tool beyond the standard CR models. In this work, we are developing such a capability for coupled atomic, molecular and plasma simulation, which will be integrated with the LANL VPIC code for plasma boundary study. Electron mobility, diffusion coefficient and electric conductivity from the simulations with the latest molecular CR data for electron-neural interactions calculated by an all-order convergent close-coupling (CCC) approach will be compared with experiment data and previous model. We aim to simulate the near-wall plasma profile including the coupled atomic and molecular collisional radiative processes in the near term and preliminary results will be discussed.
