Publication number: 20260011530Abstract: A broad beam plasma or ion source is provided, which includes an anode pole extending beyond the top surface of the cathode. A further aspect of a broad ion source includes magnets and magnetic shunts which create convex magnetic flux across and above the anode pole, which intercepts a significant portion of the magnetic flux. In another aspect, a broad beam ion source includes a magnetic surrounding cathode that prevents the magnetic flux from leaking out of the ion source. A further aspect provides a broad beam plasma source which is excited by combined DC and RF powers to create ions and reactive species to interact with specimen. Yet in a further aspect, a broad beam ion source operates simultaneously with another deposition source at the same internal pressure in a vacuum chamber for making high-quality thin films.Type: ApplicationFiled: July 3, 2024Publication date: January 8, 2026Applicants: Board of Trustees of Michigan State University, Scion Plasma, LLCInventors: Qi Hua Fan, David Stevenson, Li Qin Zhou

Patent number: 9745735Abstract: An intake nozzle fits onto the suction hose of a vacuum pumper truck. The nozzle comprises a tubular housing and the rotor within the housing near the intake end. The rotor includes a hollow cylindrical canister and spiral vanes on its exterior. Ambient air enters an air tube, penetrates the side of the housing and supplies ambient air to the interior of the canister. The air exits through outlet ports into the liquid waste as it moves past under vacuum. The injected air reduces the density of the liquid waste, speeding up the pumping process and reducing the incidence of blockages.Type: GrantFiled: June 27, 2014Date of Patent: August 29, 2017Inventors: David Stevenson, Christopher Stevenson
