Calculations of Electron Capture Cross Sections Relevant for Diagnostics of Fusion Plasmas

Research funding project
The proposed project focusses on the calculation of electron capture cross sections relevant for diagnostics in nuclear fusion research. We have a series of atomic-orbital close-coupling calculations (AOCC) in mind. The applicant obtained proficiency in this method mainly by the calculation and analysis of a benchmarking collisional system (Be4+ + H → Be3+(nl) + H +). Here the convergence of the AOCC calculation was demonstrated and an extensive analysis of total and state-selective cross sections was made. This analysis outlines the steps to be taken when looking for an optimized description of a collisional system focussing on convergence and numerical stability. We plan to calculate electron capture cross sections for high-q plasma impurities such as Arq+ or Wq+. This is a challenging project because the very large number of basis states that will be needed for converging descriptions of these collisional systems.
