On Feb. 19 and 22, the team fired Focus-Fusion-1 at 24 kV with a pressure of 8 torr of deuterium in the vacuum chamber. In some shots, they connected the angular momentum coil (AMC) to the power supply, so current could flow through it. In other shots, they left the coil circuit open, so no current could flow. The shots with the AMC connected have a neutron yield 8-10 times that of those with the AMC disconnected, so this is a large and very promising effect.
What they believe is happening is that the current in the coil is producing a small magnetic field along the axis of the device. The interaction of the currents with this field induces angular momentum—spin—in the plasma sheath. This in turn diverts the current in the sheath in the same direction as the current in the coils, amplifying the field. The angular momentum, conveyed ultimately to the tiny plasmoid, creates a centrifugal force that balances the compressive magnetic forces. The bigger the centrifugal force, the bigger the magnetic field that can be balanced and the bigger the plasmoid. However, if the centrifugal force is too big, it will prevent the plasmoid from forming at all. Thus only small fields are effective.
The Angular Momentum test was one of Eight Objectives of the Lawrenceville Plasma Physics Focus Fusion Experiments
Lawrenceville Plasma Physics (LPP) a small research and development company part way through a two-year-long experimental project to test the scientific feasibility of Focus Fusion, controlled nuclear fusion using the dense plasma focus (DPF) device and hydrogen-boron fuel. Hydrogen-boron fuel produces almost no neutrons and allows the direct conversion of energy into electricity. Success would mean thousands of times more total energy would be available and the energy would be cleaner and cheaper. LPP believes that with success they can lower the cost of energy up to 50 times.
* Test theory of axial magnetic field
The third goal is to test the theory that adding a small axial magnetic field, and thus a small amount of angular momentum, to the plasma will greatly increase the size of the plasmoids and thus the efficiency of energy transfer into the plasmoid.
Good progress is being made to another goal (1 megaAmp at 25 kilovolts), with 0.85 megaAmps at 30 kilovolts with only some of the switches firing. All 12 switches being fired should result in the excess of megaAmp at 25 kilovolts
