Magnetic Mirrors Revisited

April 23, 2017

Fusion veterans Ken Fowler, Ralph Moir and Tom Simonen have published a paper "A New Simpler Way to Obtain High Fusion Power Gain in Tandem Mirrors" in the IAEA journal Nuclear Fusion (2017, 57, 056014). The article builds on recent experiments in the Gas Dynamic Trap device at the Budker Institute of Nuclear Physics in Novosibirsk, Russia (Ivanov and Prikhodko, 2013, Plasma Physics and Controlled Fusion 55, 063001; see also talk by T. Simonen at Fusion Power Associates 2015 Annual Meeting posted at http://fire.pppl.gov/fpa15_mirror_path_simonen.pdf ). The article extends the high temperature "Kinetically Stabilized Tandem Mirror" concept favored by R. F. Post. by taking "advantage of recent advances in superconducting magnet technology to minimize the size and cost of End Plugs," and utilizing "parallel advances in gyrotrons that would enable intense electron cyclotron heating in these high field End Plugs."

The authors assert that these advances "make tandem mirrors a viable candidate to burn advanced fuels in the future, and also improves performance of deuterium-tritium (DT) fuel in the nearer term." They acknowledge that "radial losses remain an issue that will ultimately determine reactor viability."
