Abstract: A chamber cross-sectional multi-stage plasma arrangement characterized by escalating charge movement towards chamber center axis through one or more escalation stages contributing to the heating of the plasma, the centering of the plasma on the chamber axis, and creating rotation of the plasma therein. Rotation of the plasma around its axis induces a self-generated magnetic field, which in turn increases plasma stability and confinement. Some of the said stages of the multi-stage arrangement may be created by physical elements and components while others may be induced or generated by externally applying magnetic and/or electric fields or their combinations and/or by injection of electrons, ions or other plasma.

Abstract: An example method includes directing gas, via one or more first valves, from within an inner electrode to an acceleration region between the inner electrode and an outer electrode that substantially surrounds the inner electrode, directing gas, via two or more second valves, from outside the outer electrode to the acceleration region, and applying, via a power supply, a voltage between the inner electrode and the outer electrode, thereby converting at least a portion of the directed gas into a plasma saving a substantially annular cross section, the plasma flowing axially within the acceleration region toward a first end of the inner electrode and a first end of the outer electrode and, thereafter, establishing a Z-pinch plasma that flows between the first end of the outer electrode and the first end of the inner electrode. Related plasma confinement systems and methods are also disclosed herein.

Abstract: A system for generating magnetized plasma and sustaining plasma's magnetic field comprises a plasma generator for generating magnetized plasma and a flux conserver in which the generated magnetized plasma is injected and confined. A central conductor comprises an upper central conductor and a lower central conductor that are electrically connected forming a single integrated conductor. The upper central conductor and an outer electrode form an annular plasma propagating channel. The lower central conductor extends out of the plasma generator and into the flux conserver such that an end of the inner electrode is electrically connected to a wall of the flux conserver. A power system provides a formation current pulse and a sustainment current pulse to the central conductor to form the magnetized plasma, inject such plasma into the flux conserver and sustain plasma's magnetic field.

Abstract: In an example, a method of operating an ultraviolet (UV) light source includes providing a supply power to the UV light source, and activating, using the supply power, the UV light source to emit UV light during a series of activation cycles. The method also includes, during at least one activation cycle in the series, sensing the UV light emitted by the UV light source to measure an optical parameter of the UV light. The optical parameter is related to an antimicrobial efficacy of the UV light. The method further includes adjusting, based on the measured optical parameter, an electrical parameter of the supply power to maintain a target antimicrobial efficacy of the UV light over the series of activation cycles.

Abstract: An optical waveguide is formed using a gas-enclosed vessel that has an internal space in which a polyvalent ionizable gas is enclosed, a laser beam irradiation unit, and a discharge circuit that causes a pulse current to flow in the gas-enclosed vessel at an initial current value. The pulse current is increased from the initial current value to a subsequent current value greater than the initial current value, and a polyvalent ionization channel is formed in the internal space, while increasing the pulse current, by irradiating the internal space in the plasma state with a trigger laser beam generated by the pulse laser beam irradiation device. The polyvalent ionization channel expands by an inverse pinch effect after the internal space is irradiated with the trigger laser beam due to a concentration of the pulse current in the internal space.

Abstract: A spheromak is a plasma of ions and electrons formed into a toroidal shape. A spheromak plasma can include electrons and ions of nearly equal amounts such that it is essentially charge neutral. It contains large internal electrical currents and their associated internal magnetic fields arranged so that the forces within the spheromak are nearly balanced. The spheromak described herein is observed to form around an electric arc in partial atmosphere, and is observed to be self-stable with no external magnetic containment. The spheromak can be captured using a capture system. The spheromak can be accelerated through an accelerator tube.

Abstract: A system is provided for producing plasma pinch X-rays usable in X-ray lithography. Ionized heated plasma is repeatably generated in a first area directly from solid material without exploding the latter. X-rays are generated in a second area by passing high current through the plasma causing radial inward magnetic field pinching. Accurate control and improved intensity performance, and greater flexibility in selection of X-ray emitting materials, are provided by the separation of the plasma generating and the X-ray pinch generating functions. Common electrode structure is provided for plasma generating and for plasma pinching, which common electrode also provides a cylindrical plasma communication passage from the first to the second area, and provides an X-ray emission passage of desired axial orientation.

Abstract: An ionizable material is ejected in the shape of a cylindrical column from a cathode-nozzle toward an anode and subjected to a very short, high voltage pulse of electrical current having sufficient magnitude to create a high magnetic field which implodes the cylindrical column of ionizable material to a very high density plasma that emits long wave length x-rays. Accurate and reliably reproduced x-ray bursts are provided through coupling of the cathode and anode to the high voltage pulse generator without substantially degrading the pulse. The conductors between the pulse generator and the cathode and anode are of a configuration whereby a magnetic field is used to prevent the electron losses by tapering the spacing between feed conductors and shaping the feed conductors so that space-charge flow is retrapped and made usable.
