Publication number: 20210115591Abstract: A CVD single crystal diamond material suitable for use in, or as, an optical device or element. It is suitable for use in a wide range of optical applications such as, for example, optical windows, laser windows, optical reflectors, optical refractors and gratings, and etalons. The CVD diamond material is produced by a CVD method in the presence of a controlled low level of nitrogen to control the development of crystal defects and thus achieve a diamond material having key characteristics for optical applications.Type: ApplicationFiled: October 27, 2020Publication date: April 22, 2021Applicant: ELEMENT SIX TECHNOLOGIES LIMITEDInventors: HERMAN PHILIP GODFRIED, GEOFFREY ALAN SCARSBROOK, DANIEL JAMES TWITCHEN, EVERT PIETER HOUWMAN, WILHELMUS GERTRUDA MARIA NELISSEN, ANDREW JOHN WHITEHEAD, CLIVE EDWARD HALL, PHILIP MAURICE MARTINEAU

Patent number: 8241474Abstract: A method and system is disclosed for monitoring one or more characteristics associated with a fluid. An insulating layer comprising non-conducting diamond is positioned within a housing and has a surface exposed directly or indirectly to the fluid. A plurality of microelectrodes made of electrically conducting diamond each have a surface exposed directly or indirectly to the fluid. An electrical circuit in electrical communication with each of the microelectrodes is adapted to convert electrical signals from the microelectrodes into at least one signal associated with a characteristic being monitored. The sensing system is well suited to hydrocarbon wellbore related applications, but can also be used in other applications.Type: GrantFiled: June 27, 2008Date of Patent: August 14, 2012Assignee: Schlumberger Technology CorporationInventors: Li Jiang, Timothy Gareth John Jones, Clive Edward Hall
