TL;DR: In this paper, a hybrid implicit algorithm was developed to treat dense plasmas accurately, and simulations of neutralized ballistic transport showed improved transport efficiency for a 4-GeV, 4-kA Pb ion beam by including a 1013 cm−3 plasma at initialization.

TL;DR: Cuneo et al. as discussed by the authors showed that very late acceleration is not a universal aspect of wire array implosions and varied the ablation period between 46% +/-2% and 71%+/-3% of the stagnation time.

TL;DR: In this article, two breakdown mechanisms were observed in magnetic tunnel junctions having an ultrathin alumina barrier, and the results suggest that one type of breakdown occurs because of the intrinsic breakdown of a well-formed oxide barrier that can be described by the E model of dielectric breakdown.

TL;DR: In this article, the design of a 6.5-MV linear transformer driver for flash-radiography experiments is presented, and several fault modes are identified, and circuit simulations are used to determine their effect on the output pulse and other components.

TL;DR: In this article, two types of breakdown were observed: abrupt dielectric breakdown at an effective field of 10 MV/cm determined by the thickness of the tunnel barrier, and a gradual breakdown related to defects in the tunnel barriers.
