Computational Module for Charge Exchange and Ion Stripping in HIB Transport

75355-Near term Heavy Ion Fusion (HIF) experiments require the development of a set of subroutines that are suitable for the straightforward insertion into existing simulation codes. This project will develop a subroutine for one such code, LSP, which will provide lookup of charge exchange and ion stripping, especially multi-electron stripping transport. In Phase I, data will be mined from experiments, handbooks, and calculation results to build a database. Further numerical calculations will be performed to fill in gaps. Representative stripping and recombination reactions will be implemented in a prototype code. The performance of the prototype code will be evaluated and recommendations for a reaction matrix, to be included in the expanded Phase II code, will be developed. Commercial Applications and Other Benefits as described by the awardee: The research should enhance the capabilities of the LSP code for HIF projects and support the building of a demonstration reactor for Inertial Fusion Energy in the future.
