Patent number: 10998160Abstract: A pair of straight or angularly oriented flat emitters formed of an electron emissive material are positioned on an emitter support structure and are electrically connected to one another regardless of the mounting structure on which the emitters are positioned. The electrical connections between the emitters are formed directly between the emitters using electrically conductive material members that are placed between and affixed to the emitters to provide the electrical pathway or connection therebetween the emitters after formation of the emitters. These electrical connection members form an electrical connection between the angled pair of emitters separately from an emitter support structure on the cathode, such that the electrical connection members and angled emitters including the connection members can separate the mechanical architecture of the cathode assembly from the electrical architecture, thereby creating a simplified construction for the cathode assembly and associated x-ray tubes.Type: GrantFiled: August 21, 2018Date of Patent: May 4, 2021Assignee: General Electric CompanyInventors: Gregory Steinlage, Andrew Marconnet, Sandhya Abhivandana Dammu, Evan Lampe, Edward Emaci, Michael Utschig, Donald Allen, Richard Brogan

Patent number: 10910187Abstract: At least one emitter formed of an electron emissive material is positioned on a cathode assembly and is readily and reliably connected to at least one mounting member of the cathode assembly. The connections between the at least one emitter and an emitter support structure are formed directly between the at least one emitter and the emitter support structure by utilizing the at one mounting member on the emitter support structure that are positioned adjacent the at least one emitter and heated to secure the at least one emitter to the emitter support structure by welding the at least one mounting member to the at least one emitter and emitter support structure.Type: GrantFiled: September 25, 2018Date of Patent: February 2, 2021Assignee: General Electric CompanyInventors: Andrew Marconnet, Gregory Steinlage, Sandhya Abhivandana Dammu, Evan Lampe, Donald Allen, Michael Utschig, William Scott, David Bateman

Publication number: 20200350137Abstract: An x-ray tube includes an electron emitter and a cathode cup having a recess that holds the electron emitter. The recess has a bottom surface, and a shield is positioned in the recess between the electron emitter and the bottom surface. The shield is configured to receive deposited sublimated emitter material and to maintain the sublimated emitter material away from the electron emitter.Type: ApplicationFiled: May 1, 2019Publication date: November 5, 2020Applicant: GE Precision Healthcare LLCInventors: Donald Robert Allen, Sandhya Dammu, Andrew Marconnet, Gregory Steinlage

Patent number: 10636608Abstract: A flat emitter for uses within an x-ray tube is formed of an electron emissive material that includes one or more stress compensation features capable of reducing the total stress in the flat emitter due to thermal expansion and/or centrifugal acceleration force. The one or more stress compensation features of the flat emitter for reducing the total stress in the flat emitter are formed directly on the flat emitter, are formed on the support structure for the flat emitter and connected to the flat emitter, or a combination thereof.Type: GrantFiled: June 5, 2017Date of Patent: April 28, 2020Assignee: General Electric CompanyInventors: Evan Lampe, Edward Emaci, Andrew Marconnet, Michael Hebert, Michael Utschig

Patent number: 10529526Abstract: In the present invention, a flat emitter is formed from emitter material preforms shaped as thin sheets of the emitter material. These sheets are subjected to various levels and/or amounts of mechanical working during their initial formation and are bonded to one another to create a preform having the desired thickness. The preform including the bonded sheets is subsequently worked to shape the preform into the desired configuration for the emitter. The working of the sheets of emitter material utilized to create the preform and the working of the preform to form the emitter provide a highly creep-resistant emitter that significantly improves the operation and useful life of the resulting emitter.Type: GrantFiled: November 16, 2018Date of Patent: January 7, 2020Assignee: General Electric CompanyInventors: Andrew Marconnet, Gregory A. Steinlage
