The PAMS/GDP Process for Production of ICF Target Mandrels
B.W. McQuillan,Abbas Nikroo,D. A. Steinman,Fred Elsner,D. G. Czechowicz,M. Hoppe,M. Sixtus,W. J. Miller +7 more
TL;DR: In this paper, an improved process for the production of ICF target mandrels was developed, which is capable of making GDP shells with a wide size range (from 300 < o.d. < 2700 µm) and independently controlled wall thickness (from 1 to 30 µm).
Journal ArticleDOI

Andrea Kritcher,Damian Swift,Tilo Döppner,Benjamin Bachmann,Lorin X. Benedict,Gilbert Collins,Jonathan L. DuBois,Fred Elsner,Gilles Fontaine,Jim Gaffney,Sebastien Hamel,Amy Lazicki,W. R. Johnson,Natalie Kostinski,Dominik Kraus,Dominik Kraus,Michael MacDonald,Brian Maddox,M. Martin,Paul Neumayer,A. Nikroo,Joseph Nilsen,Bruce Remington,Didier Saumon,P. A. Sterne,Wendi Sweet,Alfredo A. Correa,Heather D. Whitley,Roger Falcone,Siegfried Glenzer +29 more
TL;DR: Researchers have measured the equation of state of hydrocarbon in a high-density regime, which is necessary for accurate modelling of the oscillations of white dwarf stars and predicts an increase in compressibility due to ionization of the inner-core orbitals of carbon.
Journal ArticleDOI
Robustness to hydrodynamic instabilities in indirectly driven layered capsule implosions
Brian Haines,R. E. Olson,W. Sweet,S. A. Yi,Alex Zylstra,Paul A. Bradley,Fred Elsner,H. Huang,R. Jimenez,John Kline,C. Kong,George A. Kyrala,R. J. Leeper,R. R. Paguio,S. Pajoom,Robert R. Peterson,M. Ratledge,Neal Rice +17 more
TL;DR: In this article, the authors report on a high convergence ratio liquid layer capsule implosion performed on the National Ignition Facility and contrast it to two previously reported layered implosions, in order to better understand how the capsule design impacts the hydrodynamic stability properties.
Journal ArticleDOI
Development of High Quality Poly(α-Methylstyrene) Mandrels for NIF
M. Takagi,Robert Cook,B.W. McQuillan,Fred Elsner,Richard B. Stephens,Abbas Nikroo,Jane Gibson,Sally Paguio +7 more
TL;DR: In this article, a method for making spherical poly(α-methylstyrene) (PαMS) mandrels was developed. The process utilizes a small amount (< 0.1wt%) of high-molecular-weight poly(acrylic acid) (PA) in th...
Journal ArticleDOI
Understanding the Critical Parameters of the PAMS Mandrel Fabrication Process
TL;DR: In this paper, the authors describe the reasoning that leads them to focus on the so-called curing process where a solid poly(α-methylstyrene) (PAMS) shell is formed from the initial solution phase.
