Slowing of magnetic reconnection concurrent with weakening plasma inflows and increasing collisionality in strongly-driven laser-plasma experiments
Michael Rosenberg,Chikang Li,William Fox,Alex Zylstra,Christian Stoeckl,Fredrick Seguin,Johan Frenje,R. D. Petrasso +7 more
TL;DR: It is demonstrated that powerful initial plasma flows are not sufficient to force a complete reconnection of magnetic fields, even in the strongly driven regime.
Impact of stalk on directly driven inertial confinement fusion implosions
M. Gatu Johnson,Patrick Adrian,Karen S. Anderson,Brian Appelbe,Jeremy Chittenden,Aidan Crilly,D. H. Edgell,Chad Forrest,Johan Frenje,V. Yu. Glebov,Brian Haines,Igor V. Igumenshchev,D. Jacobs-Perkins,R. Janezic,Neel Kabadi,J. P. Knauer,Brandon Lahmann,Owen Mannion,F. J. Marshall,T. Michel,Fredrick Seguin,R. C. Shah,Christian Stoeckl,Christopher Walsh,R. D. Petrasso +24 more
TL;DR: In this article, an experiment on the OMEGA laser with intentional offsets at varying angles to the capsule stalk mount is described, which clearly demonstrates the impact of the stalk mount on implosion dynamics.
Proton Radiography of Inertial Fusion Implosions
J. R. Rygg,Fredrick Seguin,Chikang Li,Johan Frenje,Mario Manuel,R. D. Petrasso,Riccardo Betti,J. A. Delettrez,O. V. Gotchev,J. P. Knauer,David D. Meyerhofer,F. J. Marshall,Christian Stoeckl,Wolfgang Theobald +13 more
TL;DR: A distinctive way of quantitatively imaging inertial fusion implosions has resulted in the characterization of two different types of electromagnetic configurations and in the measurement of the temporal evolution of capsule size and areal density.
Effect of Strongly Magnetized Electrons and Ions on Heat Flow and Symmetry of Inertial Fusion Implosions.
Arijit Bose,J. Peebles,C. A. Walsh,Johan Frenje,Neel Kabadi,Patrick Adrian,Graeme Sutcliffe,M. Gatu Johnson,Cameron A. Frank,J. R. Davies,Riccardo Betti,V. Yu. Glebov,F. J. Marshall,Susan Regan,Christian Stoeckl,E. M. Campbell,Hong Sio,John Moody,Aidan Crilly,Brian Appelbe,J. P. Chittenden,Stefano Atzeni,F. Barbato,Antonino Forte,C. K. Li,Fredrick Seguin,R. D. Petrasso +26 more
TL;DR: In this article , the authors observed that magnetization produces a significant increase in the implosion oblateness (a 2.5× larger P2 amplitude in x-ray self-emission images) compared with reference experiments with identical drive but with no field applied.
Measurements of fuel and ablator ρR in Symmetry-Capsule implosions with the Magnetic Recoil neutron Spectrometer (MRS) on the National Ignition Facility.
M. Gatu Johnson,Johan Frenje,C. K. Li,Fredrick Seguin,R. D. Petrasso,R. Bionta,Daniel Casey,J. A. Caggiano,Robert Hatarik,Hesham Khater,Daniel Sayre,J. P. Knauer,T. C. Sangster,Hartmut Herrmann,J. D. Kilkenny +14 more
TL;DR: In this article, the authors used the Magnetic Recoil neutron Spectrometer (MRS) measurements of DT-fuel and CH-ablator ρR in DT gas-filled symmetry-capsule implosions at the National Ignition Facility (NIF) to diagnose NIF DT implosion.
