Optical Imaging on Z LDRD: Design and Development of Self-Emission and Debris Imagers

Yager-Elorriaga, David A.; Montoya, Michael M.; Bliss, David E.; Ball, Christopher R.; Atencio, Phillip M.; Carpenter, Brian C.; Fuerschbach, Kyle H.; Fulford, Karin W.; Lamppa, Derek C.; Lowinske, Michael C.; Lucero, Larry M.; Patel, Sonal P.; Romero, Anthony R.; Tanbakuchi, Anthony; Breznik-Young, Bonnie B.

We present an overview of the design and development of optical self-emission and debris imaging diagnostics for the Z Machine at Sandia National Laboratories. These diagnostics were designed and implemented to address several gaps in our understanding of visibly emitting phenomenon on Z and the post-shot debris environment. Optical emission arises from plasmas that form on the transmission line that delivers energy to Z loads and on the Z targets themselves; however, the dynamics of these plasmas are difficult to assess without imaging data. Addressing this, we developed a new optical imager called SEGOI (Self-Emission Gated Optical Imager) that leverages the eight gated optical imagers and two streak cameras of the Z Line VISAR system. SEGOI is a low cost, side-on imager with a 1 cm field of view and 30-50 µm spatial resolution, sensitive to green light (540-600 nm). This report outlines the design considerations and development of this diagnostic and presents an overview of the first diagnostic data acquired from four experimental campaigns. SEGOI was fielded on power flow experiments to image plasmas forming on and between transmission lines, on an inertial confinement fusion experiment called the Dynamic Screw Pinch to image low density plasmas forming on return current posts, on an experiment designed to measure the magneto Rayleigh-Taylor instability to image the instability bubble trajectory and self-emission structures, and finally on a Magnetized Liner Inertial Fusion (MagLIF) experiment to image the emission from the target. The second diagnostic developed, called DINGOZ (Debris ImagiNG on Z), was designed to improve our understanding of the post-shot debris environment. DINGOZ is an airtight enclosure that houses electronics and batteries to operate a high-speed (10-400 kfps) camera in the Z Machine center section. We report on the design considerations of this new diagnostic and present the first high-speed imaging data of the post-shot debris environment on Z.

Enhancing performance of magnetized liner inertial fusion at the Z facility

Physics of Plasmas

Slutz, S.A.; Gomez, Matthew R.; Hansen, Stephanie B.; Harding, Eric H.; Hutsel, Brian T.; Knapp, P.F.; Lamppa, Derek C.; Awe, T.J.; Ampleford, David A.; Bliss, David E.; Chandler, Gordon A.; Cuneo, M.E.; Geissel, Matthias G.; Glinsky, Michael E.; Harvey-Thompson, Adam J.; Hess, Mark H.; Jennings, C.A.; Jones, Brent M.; Laity, G.R.; Martin, M.R.; Peterson, Kyle J.; Porter, John L.; Rambo, Patrick K.; Rochau, G.A.; Ruiz, Carlos L.; Savage, Mark E.; Schwarz, Jens S.; Schmit, Paul S.; Shipley, Gabriel A.; Sinars, Daniel S.; Smith, Ian C.; Vesey, Roger A.; Weis, M.R.

The Magnetized Liner Inertial Fusion concept (MagLIF) [Slutz et al., Phys. Plasmas 17, 056303 (2010)] is being studied on the Z facility at Sandia National Laboratories. Neutron yields greater than 1012 have been achieved with a drive current in the range of 17-18 MA and pure deuterium fuel [Gomez et al., Phys. Rev. Lett. 113, 155003 (2014)]. We show that 2D simulated yields are about twice the best yields obtained on Z and that a likely cause of this difference is the mix of material into the fuel. Mitigation strategies are presented. Previous numerical studies indicate that much larger yields (10-1000 MJ) should be possible with pulsed power machines producing larger drive currents (45-60 MA) than can be produced by the Z machine [Slutz et al., Phys. Plasmas 23, 022702 (2016)]. To test the accuracy of these 2D simulations, we present modifications to MagLIF experiments using the existing Z facility, for which 2D simulations predict a 100-fold enhancement of MagLIF fusion yields and considerable increases in burn temperatures. Experimental verification of these predictions would increase the credibility of predictions at higher drive currents.
