Proposal of Flexible Atomic and Molecular Process Management for Monte Carlo Impurity Transport Code Based on Object Oriented Method

摘要

A Monte Carlo impurity transport code based on object-oriented method has been developed. Edge plasma in fusion devices has a lot of impurity atoms and molecules such as hydrocarbon species, C_xH_y due to low electron temperature in the edge. Various atomic/molecular processes have been considered in the edge plasma region and we need to determine which process is essential in edge plasma conditions. To take such complicated processes into account in a systematic way, Monte Carlo impurity simulation, which has a strong flexibility in dealing with various atomic and molecular processes, would be useful. By employing the object-oriented method in the simulation code, we can handle arbitrary atomic and molecular processes.
