Patent number: 10352811Abstract: A cold cathode ionization vacuum gauge includes an extended anode electrode and a cathode electrode surrounding the anode electrode along its length and forming a discharge space between the anode electrode and the cathode electrode. The vacuum gauge further includes an electrically conductive guard ring electrode interposed between the cathode electrode and the anode electrode about a base of the anode electrode to collect leakage electrical current, and a discharge starter device disposed over and electrically connected with the guard ring electrode, the starter device having a plurality of tips directed toward the anode and forming a gap between the tips and the anode.Type: GrantFiled: September 22, 2017Date of Patent: July 16, 2019Assignee: MKS Instruments, Inc.Inventors: Gerardo A. Brucker, Timothy C. Swinney, Brandon J. Kelly, Alfred A. Funari, Michael N. Schott, Kristian S. Schartau

Patent number: 10337940Abstract: A cold cathode ionization gauge includes multiple cathodes providing different spacings between the cathodes and an anode. The multiple cathodes allow for pressure measurements over wider ranges of pressure. A first cathode with a larger spacing may provide current based on Townsend discharge; whereas, a second cathode having a smaller spacing may provide current based on both Townsend discharge at higher pressures and on Paschen's Law discharge at still higher pressures. A feature on the second cathode may support Paschen's Law discharge. Large resistances between the cathodes and a return to power supply enable control of output profiles to extend the pressure ranges with accurate responses and avoid output minima. Pressure measurements may be made based on currents from respective cathodes dependent on the outputs of the cathodes through the wide pressure range of measurement.Type: GrantFiled: April 27, 2017Date of Patent: July 2, 2019Assignee: MKS Instruments, Inc.Inventors: Timothy C. Swinney, Clinton L. Percy, Duane W. Marion, Brandon J. Kelly
