High-Yield Z-Pinch Thermonuclear Neutron Source
Introduction: Neutron beams are useful for many applications, from noninvasive imaging and characterization of materials to producing medical isotopes and detecting hidden explosive devices. Some applications require high-energy neutrons created in fusion nuclear reactions between deuterium (D) and tritium (T). To achieve thermal fusion, deuterium or DT plasma must be heated to about 10 8 K, wh...
متن کاملTarget design for high fusion yield with the double Z-pinch-driven hohlrauma..
A key demonstration on the path to inertial fusion energy is the achievement of high fusion yield !hundreds of MJ" and high target gain. Toward this goal, an indirect-drive high-yield inertial confinement fusion !ICF" target involving two Z-pinch x-ray sources heating a central secondary hohlraum is described by Hammer et al. #Phys. Plasmas 6, 2129 !1999"$. In subsequent research at Sandia Nati...
متن کاملZ-pinch Driven Isentropic Compression for Inertial Fusion
The achievement of high gain with inertial fusion requires the compression of hydrogen isotopes to high density and temperatures. High densities can be achieved most efficiently by isentropic compression. This requires relatively slow pressure pulses on the order of 10-20 nanoseconds; however, the pressure profile must have the appropriate time history [J. Nuckolls et. al. Nature, 239, 139, 197...
متن کاملSchlieren Measurements of a High Density Z-Pinch
The dense plasma phase of a dynamic z-pinch working at a high filling pressure is studied. By using the Schlieren-technique it is found that the compressed plasma column, though macroscopically stable for times less than 1 /us develops quickly from a homogeneous state to a turbulent one with a perturbation scale length of typically some millimeters. Quantitative measurements of light deflection...
متن کاملOptimum driving a Z-pinch for soft X-Ray lasers
A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...
