摘要：
SEMILLAC is a fast, yet highly accurate method to calculate ionic population distributions in plasmas at a given electron temperature and density. SEMILLAC solves rate equations for non-relativistic configurations population distributions. It considers electron collisional, radiative and autoionizing atomic processes. The code is designed to be highly versatile so it can be used for modeling a wide range of laboratory plasmas. The population distributions can be calculated for steady state or time dependent conditions, with or without the presence of a radiation field. SEMILLAC is designed to be used as a tool for population distributions calculations and spectroscopic modeling of plasmas. Our aim is to get high accuracy while keeping the code fast enough to be used for standard PC calculations. At the heart of our method, average transitions energies and rate coefficients are calculated for a restricted set of simple non-relativistic ionic configurations using the HULLAC code. We then use this basic set to calculate energies and rates coefficients of more complex, multiply excited configurations. (C) 2013 Elsevier B.V. All rights reserved.
