Status of the Z pulsed power driver

Demonstration of thermonuclear conditions in magnetized liner inertial fusion experimentsa)

“…During the laser heating stage, several kJ of energy are delivered to the target; for comparison, Z can deliver several MJ to a target during an implosion. 30 The substantial difference in energy delivered between these two cases requires separate experiments in order to diagnose the low amplitude signals generated during the laser heating stage. The laser heating experiments utilized the ABZ system and ZBL without the Z drive current.…”

“…The Z machine stores up to 22 MJ of electrical energy and is capable of delivering 27 MA with a 100 ns risetime to a well-matched load. 30,31 ZBL is a TW-class, multi-KJ, frequency-doubled (527 nm) Nd:glass laser. 32 The ABZ system consists of a 900 kJ capacitor back and a pair of Helmholtz-like coils, which can magnetize cm-scale targets to 10-30 T. 33 Fully integrated MagLIF experiments utilize all three of these capabilities.…”

Experimental Demonstration of Fusion-Relevant Conditions in Magnetized Liner Inertial Fusion

“…The Z Beamlet laser (ZBL), a 2.5 kJ, 1 TW, frequency-doubled Nd:YAG laser [19], heated the deuterium fuel. The 100 ns risetime, 19 MA current of the Z Machine [20,21] drove the liner, which compressed the fuel. The experimental drive current, experimental laser power, and simulated liner trajectory [10] are plotted in Fig.…”

“…55). 1 Note the similarity between Eq. 57 for a radial electric field in cylindrical geometry (Er(r) = (1/ 0 )Q/(2πr)) and Eq.…”

“…These systems often come in the form of large pulsedpower facilities or large laser facilities. Present state-of-the-art HEDP facilities include the Z pulsed-power facility at Sandia National Laboratories [1], [2], the OMEGA and OMEGA-EP laser facilities at the University of Rochester's Laboratory for Laser Energetics [3], [4], and the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory [5], [6]. These facilities support a variety of programs in stockpile stewardship and basic science.…”
