Fredrick Seguin,Johan Frenje,Chikang Li,Damien Hicks,S. Kurebayashi,J. R. Rygg,B. E. Schwartz,R. D. Petrasso,S. Roberts,J. M. Soures,D. D. Meyerhofer,T. C. Sangster,J. P. Knauer,C. Sorce,V. Yu. Glebov,Christian Stoeckl,T. W. Phillips,R. J. Leeper,K. A. Fletcher,S. Padalino +19 more
TL;DR: Boehly et al. as mentioned in this paper used CR-39 nuclear track detectors in conjunction with magnets and/or special ranging filters for high-resolution spectrometry of charged particles from inertial confinement-fusion (ICF) experiments.
Journal ArticleDOI
Measuring E and B fields in laser-produced plasmas with monoenergetic proton radiography.
Chikang Li,Fredrick Seguin,Johan Frenje,J. R. Rygg,R. D. Petrasso,Richard Town,Peter Amendt,S. P. Hatchett,Otto Landen,A. J. Mackinnon,P. K. Patel,Vladimir Smalyuk,T. C. Sangster,J. P. Knauer +13 more
TL;DR: Electromagnetic (E/B) fields generated by the interaction with plasmas of long-pulse, low-intensity laser beams relevant to inertial confinement fusion have been measured for the first time using novel monoenergetic proton radiography methods.
Journal ArticleDOI
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.
Journal ArticleDOI
Observation of megagauss-field topology changes due to magnetic reconnection in laser-produced plasmas.
Chikang Li,Fredrick Seguin,Johan Frenje,J. R. Rygg,R. D. Petrasso,Richard Town,Otto Landen,J. P. Knauer,Vladimir Smalyuk +8 more
TL;DR: Quantitative field maps reveal precisely and directly, for the first time, changes in the magnetic topology due to reconnection in a high-energy-density plasma.

TL;DR: The High-Foot platform as discussed by the authors manipulates the laser pulse-shape coming from the National Ignition Facility laser to create an indirect drive 3-shock implosion that is significantly more robust against instability growth involving the ablator and also modestly reduces implosion convergence ratio.
