R. E. Olson,John L. Porter,Gordon A. Chandler,D. L. Fehl,D. O. Jobe,R. J. Leeper,Maurice Keith Matzen,J. S. McGurn,D.D. Noack,L. E. Ruggles,P. Sawyer,Jose A. Torres,M. Vargas,D. M. Zagar,H. N. Kornblum,T. J. Orzechowski,D. W. Phillion,L. J. Suter,A. R. Thiessen,R. J. Wallace +19 more
TL;DR: In this article, the authors used the Saturn pulsed-power-driven z pinch to drive hohlraums of full NIF ignition scale size at radiation temperatures and time scales comparable to those required for the low-power foot pulse of an ignition capsule.

TL;DR: Particle Beam Fusion Accelerator II as discussed by the authors is a light-ion fusion accelerator that is presently capable of irradiating a 6mm-diam sphere with ∼50 kJ of 5.5MeV protons in ∼15 ns.

TL;DR: A news diagnostic package has been developed for the Sandia National Laboratories' PBFA-II accelerator as mentioned in this paper, which emphasizes off-axis Rutherford-scattering measurements and includes the following: off-and on-axis multi-frame dE/dx ion pinhole cameras, an off-domain energy-resolved ion movie camera, an on-domain time-resolution ion movie cameras, a one-dimensional imaging capability, a time-integrated and timeresolved K{alpha} x-ray pinhole camera, a plasma visible spectroscopy diagnostic, an elliptical crystal

TL;DR: In this article, the authors performed experiments using proton beams to heat foam-filled cylinders on the Particle Beam Fusion Acceleration II (PBF II), and the results of broadband spectral measurements on bolometers and xray diodes provided qualitative agreement with LASNEX predictions of target features such as Au motion and soft x-ray emission profile, consistent with a total beam deposition of 40-50 kJ and power depositions of approximately 180 TW/g.
