  • Patent number: 12154763
    Abstract: An ion source has an arc chamber defining an arc chamber volume. A reservoir is coupled to the arc chamber, defining a reservoir volume. The reservoir receives a source species to define a liquid within the reservoir volume. A conduit fluidly couples the reservoir volume to the arc chamber volume. First and second openings of the conduit are open to the respective reservoir and arc chamber volume. A heat source selectively heats the reservoir to melt the source species at a predetermined temperature. A liquid control apparatus controls a first volume of the liquid within the reservoir volume to define a predetermined supply of the liquid to the arc chamber volume. The liquid control apparatus is a pressurized gas source fluidly coupled to the reservoir to supply a gas to the reservoir and provide a predetermined amount of liquid to the arc chamber.

  • Patent number: 12133938
    Abstract: An ultraviolet cyclonic fluid dosing system for disinfecting fluid materials is described. The dosing system includes a dosing chamber that includes a cylindrical chamber portion and a conical chamber portion. The cylindrical chamber portion has a fluid outlet and a fluid inlet that causes fluid material to enter the upper chamber and travel a helical path down through the upper chamber and into the conical chamber, from where it travels upward in exits through the fluid outlet.
