Abstract: Examples of a system for generating and compressing magnetized plasma are disclosed. The system comprises a plasma generator with a first closed end and an outlet, and a flux conserving chamber that is in tight fluid communication with the outlet of the plasma generator such that the generated plasma is injected into an inner cavity of the flux conserving chamber. An elongated central axial shaft is also provided such that the central shaft extends through the outlet of the plasma generator into the flux conserver. The end of the central shaft in connected to the flux conserver. A power source that comprises a formation power circuit and a shaft power circuit is provided to provide a formation power pulse to the plasma generator to generate magnetized plasma, and a shaft power pulse to the central axial shaft to generate a toroidal magnetic field into the plasma generator and the flux conserving chamber. The duration of the shaft power pulse is longer than the duration of the formation power pulse to maintain plasma q-profile at a pre-determined range. During plasma compression the shaft power pulse is increased to match the raise of the plasma poloidal field due to the compression and thus maintain the q-profile of the plasma.

Abstract: Examples of a device for gettering and surface conditioning are disclosed. The device comprises an elongated tube with a closed first end, a second end and a body extending between the first end and the second end. The body defines an inner cavity of the tube in which a heating device is inserted. The tube is inserted into a vessel so that the first end is positioned within the vessel. A solid metal is mounted closely to the tube in a region surrounding the heating device and a meshed screen is mounted over the solid metal and secured to the tube. When the heating device is on, the heat transfers through the tube's wall into the solid metal melting and vaporizing it, so that the metal vapors travel and coat onto vessel's surfaces. The device can also be used in producing metal alloys such as lead lithium alloys.
