Pulsed-electric-power drivers might be an efficient, low-tech alternative to
lasers in the quest for an inertial-confinement thermonuclear reactor.

A group at Sandia National Laboratories in Albuquerque, New Mexico, has
announced the first yield of thermonuclear neutrons from an
inertial-confinement fusion scheme that does not involve lasers. At the April
meeting of the American Physical Society in Philadelphia, Ramon Leeper
reported that he and his colleagues had performed an experiment at
Sandia's pulsed-power "Z Machine" (see Physics Today, June 1998, page
56) that produced some 3 × 10^10 thermonuclear neutrons in the implosion
of a small, spherical capsule of deuterium gas.

Thermonuclear weapons are powered by the fusion of deuterons with
tritium nuclei. For almost half a century now, physicists have been seeking
to harness DT fusion for the production of electric power. But the creation
of a confined DT plasma hot and dense enough to ignite a self-sustaining
burn remains an elusive goal.
