A numerical simulation package, the Lee Model was developed for the network but has proven successful to simulate all plasma focus devices. Recently numerical experiments using this code have uncovered a pinch current limitation effect and given a fresh outlook to neutron scaling laws from sub-kJ to multi-megajoule devices. The latest version is now downloadable as Universal Plasma Focus Laboratory Facility based at Centre for Plasma Research, INTI International University [https://web.archive.org/web/20130403014235/http://newinti.edu.my/main/. In association with the AAAPT, the Institute for Plasma Focus Studies [http://www.plasmafocus.net] was founded on 25 February 2008 to promote correct and innovative usage of the Lee Model and to encourage dense plasma focus numerical experiments.
