Compression of puffing deuterium by neon plasma sheath on plasma focus device

The experimental research of fusion DD reaction was provided on the plasma focus device at the current of 2 MA in the approach with the MagLIF conception. The deuterium injected from the gas-puff in the axis of the anode and compressed by neon plasma sheath was studied with the multiframe x-ray and interferometry diagnostics. The total neutron yield at the level of 10

per shot was registered at the compression of about 7 µg/cm of the deuterium from the gas-puff by about 23 µg/cm of the neon plasma sheath. The addition of the puffing deuterium to the filling neon in the chamber decreased the soft X-ray emission about two orders. This decrease can be explained by the absence of the neon and the presence of the deuterium in the central structures during their formation and transformation. The separation of both gases should be caused by internal closed currents magnetizing the plasma. The neutrons were produced both at the initial phase of stagnation, as well as at a later time in the evolution of instabilities.
