SGEMP Algorithm Development and Demonstration for ICEPIC
- Confluent Sciences, LLC, Albuquerque, NM (United States)
Algorithms designed to facilitate calculation of gas-modified System-Generated Electromagnetic Pulse (SGEMP) phenomena have been developed for use in ICEPIC. Improvements and extensions of these and related models are considered for helping them be more widely applicable for SGEMP modeling. Confluent Sciences has developed a Buneman-Villasenor unit test tool for assessing particle merge algorithms and has applied that to several candidate algorithms. Statistical analysis of Maxwellian and near-Maxwellian velocity distribution functions has been used to understand limits and tradeoffs of particle merging. Collisional phenomena and plasma models that relieve the burden of a fully kinetic approach have also been developed and assessed.
