Patent number: 11355327Abstract: An ion pump with a housing enclosing an interior, a gas inlet having a through-hole extending into the interior of the ion pump, at least one cathode, at least one anode positioned in proximity to the at least one cathode, a magnet disposed on an opposite side of the at least one cathode from the anode, and a blocking shield disposed between the gas inlet and the at least one cathode. The blocking shield is electrically connected to the at least one anode. An associated method installs the blocking shield by inserting components of the blocking shield assembly through the gas inlet, and assembling (inside the interior of the ion pump) the inserted components to form the blocking shield.Type: GrantFiled: December 18, 2019Date of Patent: June 7, 2022Assignee: Agilent Technologies, Inc.Inventors: Cristian Maccarrone, Chiara Paolini, Enrica Carbonero, Paolo Manassero

Patent number: 7354254Abstract: A compact turbomolecular vacuum pump (1) is driven by a cup-type motor (8). The cup-shaped rotor of the motor is preferably integrated into the pump rotor (14) and may define corresponding pumping stages, for instance Holweck stages, wherein the stators (11, 12) of said stages being preferably obtained by superimposing stator rings (11?, 12?).Type: GrantFiled: May 28, 2004Date of Patent: April 8, 2008Assignee: Varian, S.p.A.Inventors: Romina Silvia Gotta, Cinzia Del Missier, Cristian Maccarrone, Fausto Casaro

Patent number: 7059192Abstract: A pressure sensor is a micro-electro-mechanical vibrating device, with a silicon substrate (15; 15?) onto which a single-layer or multilayer vibrating assembly (121; 221; 321) is formed. It comprises an electrode (21; 21?), which makes the assembly to oscillate relative to the substrate at the resonance frequency or at another known frequency, and a detector for detecting the actual frequency and/or amplitude of said oscillation. The actual frequency and/or amplitude are affected by the conditions, in particular the pressure, of the external environment and the variations of the frequency and amplitude with respect to the values set by the electrode is used to measure pressure variations in the surrounding environment.Type: GrantFiled: October 22, 2004Date of Patent: June 13, 2006Assignee: Varian S.p.A.Inventors: Raffaele Correale, Cristian Maccarrone, Mario Busso

Publication number: 20050201882Abstract: A vacuum pumping system has at least two vacuum pumping devices with vacuum pumps, local electronic control units for monitoring and controlling the operating parameters of the pumps and a control station remotely located relative to the vacuum pumping devices. The control station is equipped with a remote control unit. The remote control unit and local control units are equipped with wireless communication modules for communicating data and commands and controlling the operation of the vacuum pumping devices. The wireless communication module of the remote control unit directly communicates with the wireless communication modules of the local control units.Type: ApplicationFiled: March 11, 2005Publication date: September 15, 2005Inventors: Cristian Maccarrone, Massimiliano Titolo
