摘要：

Experiments on the Z accelerator with deuterium gas puff implosions have produced up to 3.9x10(13) (+/- 20%) neutrons at 2.34 MeV (+/- 0.10 MeV). Experimentally, the mechanism for generating these neutrons has not been definitively identified through isotropy measurements, but activation diagnostics suggest multiple mechanisms may be responsible. One-, two-, and three-dimensional magnetohydrodynamic (MHD) calculations have indicated that thermonuclear outputs from Z could be expected to be in the (0.3-1.0)x10(14) range. X-ray diagnostics of plasma conditions, fielded to look at dopant materials in the deuterium, have shown that the stagnated deuterium plasma achieved electron temperatures of 2.2 keV and ion densities of 2x10(20) cm(-3), in agreement with the MHD calculations.
