Abstract Text:
We propose a new acoustic magnetized target fusion (MTF) driver. A 2 m diameter quasi spherical tank is filled with LiPb. The fluid is spun to open a vertical vortex tube in the center of the tank. Two spheromaks of reversed helicity are injected in the tube from the top and bottom. They merge in the center of the tank to form an FRC of 1E17 cm-3 and 100 eV. The destruction of the toroidal magnetic field provides good ion heating just prior to compression. The tank is surrounded by pneumatic cylinders that accelerate steel pistons to 100 m/s. The pistons impact the surface of the tank; launching a 20 kBar acoustic wave that focuses to the center, collapses the vortex and compresses the plasma to thermonuclear conditions. Simulations indicate a collapsing speed of 2.5 km/s, stagnation pressure of 4 Mbar at a density of 1E20 cm-3 producing an overall energy gain of 6 for an initial acoustic energy of 100 MJ and a radial compression of 10. An acoustic MTF power plant would produce ~ 100 MW electric at a repetition rate of ~1 Hz. The 100% coverage by the LiPb provides good tritium re-breeding. The very low cost of pneumatic energy and the good neutron shielding of the machine by the LiPb lead to an attractive and economically reasonable power plant. The results of a small scale experiment using an acoustically compressed plasma will also be presented. A small DD fusion yield of 2000 neutrons was observed.
