Plasma Physics (Physics/ECE/NE 922) Seminar
Magnetic Mirror Fusion Game Changing Discoveries
Time: 12:00 pm
Place: 2241 Chamberlin Hall
Speaker: Tom Simonen, Michigan Tech
Abstract: Scientific results from the Russian Gas Dynamic Trap (GDT) experiment [1] and technological developments from ITER R&D motivate examination of new magnetic mirror confinement fusion concepts. This talk will describe advances in the understanding of the physics [2] of axisymmetric MHD- stability, ion cyclotron micro-stability and axial electron temperature confinement as well as developments in ITER of high-field superconducting magnets, high-frequency MW level microwave gyrotrons, and 1 MeV energy neutral beams all of which are applicable to mirror systems. Favoring high ion temperatures, we note that mirrors provide the possibility of burning advanced fuel such as DD [3].
Footnote: During the 1980's the Wisconsin Phaedrus experiment played a significant role in developing the understanding of mirror physics [4] and, more recently, collaborated with the GDT experiment.
