Journal ArticleDOI
ARC: A compact, high-field, fusion nuclear science facility and demonstration power plant with demountable magnets
Brandon Sorbom,Justin Ball,Timothy R. Palmer,F. J. Mangiarotti,J. M. Sierchio,Paul Bonoli,C.P. Kasten,D.A. Sutherland,Harold Barnard,Christian Bernt Haakonsen,J. Goh,Choongki Sung,Dennis G. Whyte +12 more
TL;DR: The robust, robust, compact (ARC) as discussed by the authors is the product of a conceptual design study aimed at reducing the size, cost and complexity of a combined fusion nuclear science facility (FNSF) and demonstration fusion Pilot power plant.

TL;DR: The Alcator C-Mod tokamak as discussed by the authors is a high-field toroidal confinement device that uses high-power radio frequency (RF) waves for heating and current drive with innovative launching structures.
Journal ArticleDOI
Toughening mechanisms of the elytra of the diabolical ironclad beetle
Jesus Rivera,Maryam Sadat Hosseini,David Restrepo,David Restrepo,Satoshi Murata,Drago Vasile,Dilworth Y. Parkinson,Harold Barnard,Atsushi Arakaki,Pablo D. Zavattieri,David Kisailus,David Kisailus +11 more
TL;DR: This work identifies multiscale architectural designs within the exoskeleton of the diabolical ironclad beetle, Phloeodes diabolicus, and examines the resulting mechanical response and toughening mechanisms, creating interlocking sutures from biomimetic composites that show a considerable increase in toughness compared with a frequently used engineering joint.
Journal ArticleDOI
Divertor tungsten tile melting and its effect on core plasma performance
Bruce Lipschultz,J. W. Coenen,Harold Barnard,Nathan Howard,Matthew Reinke,D.G. Whyte,G.M. Wright +6 more
TL;DR: In this paper, a discussion of the implications of melting a divertor tungsten monoblock on the ITER plasma is presented, and the results show that only 15 g of Tungsten was lost from the tile over ~100 discharges.
Journal ArticleDOI
Mapping local deformation behavior in single cell metal lattice structures
Holly D. Carlton,Jonathan Lind,Mark Messner,Nickolai A. Volkoff-Shoemaker,Harold Barnard,Nathan R. Barton,Mukul Kumar +6 more
TL;DR: In this article, high-resolution mapping of the heterogeneous structural response of single unit cells to the macro-scale loading condition was performed using synchrotron radiation micro-tomography.
