PR: American Nuclear Society welcomes Senate confirmation of Ted Garrish as the DOE’s nuclear energy secretary
Washington, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate's confirmation of Theodore “Ted” Garrish as Assistant Secretary for Nuclear Energy at the U.S. Department of Energy (DOE).
“On behalf of over 11,000 professionals in the fields of nuclear science and technology, the American Nuclear Society congratulates Mr. Garrish on being confirmed by the Senate to once again lead the DOE Office of Nuclear Energy,” said ANS President H.M. "Hash" Hashemian.

Bifurcation phenomena with confinement improvement in toroidal plasmas are briefly reviewed. After a general discussion of the formation mechanisms of improved confinement modes, the electron internal transport barrier commonly observed in stellarators is chosen here as the main subject with focus on the following aspects: the bifurcation property, the scenario of bifurcation with confinement improvement, and the confinement features. Several works to investigate the relationship between rational surfaces and barrier formation are introduced as examples to show the relation between magnetic topology and the bifurcation property. The roles of stellarators, which have a wide variety of configurations, for understanding bifurcation phenomena are discussed.
