Patent number: 10408969Abstract: Devices and methods for a rugged semiconductor radiation detector are provided. The semiconductor detector may include a hermetically sealed housing and a semiconductor disposed within the housing that has a first surface and a second surface opposite one another. A first metallization layer may at least partially cover the first surface of the semiconductor and a second metallization layer may at least partially cover the second surface of the semiconductor. The first metallization layer or the second metallization layer, or both, do not extend completely to an edge of the semiconductor, thereby providing a nonconductive buffer zone. This reduces electrical field stresses that occur when a voltage potential is applied between the first metallization layer and the second metallization layer and reduces a likelihood of electrical failure (e.g., due to arcing).Type: GrantFiled: October 18, 2018Date of Patent: September 10, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Frederic Gicquel, Olivier G.

Patent number: 9368901Abstract: A connector system for reducing particulate matter may include a first unit for supplying signals and a second unit for receiving and/or relaying the signals. The signals may be for power generation and/or communications. A coupling may be positioned between the first unit and second unit. The coupling may include a center pin attached to the first unit and for receiving a signal at a first potential. The coupling may further include an outer case attached to the first unit and for receiving a signal at a second potential. The coupling may also have a seal and a spring. The seal and spring may surround the outer case. The spring may engage the second unit and may pass signals between the first unit and the second unit. The spring may comprise a canted coil spring for supporting load forces and for passing electrical current.Type: GrantFiled: March 14, 2013Date of Patent: June 14, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Frederic Gicquel

Patent number: 9263222Abstract: A radiation generator may include a generator housing, a target electrode carried by the generator housing, a charged particle source carried by the generator housing to direct charged particles at the target electrode based upon an accelerating potential, and a suppressor electrode carried by the generator housing having an opening therein to permit passage of charged particles to the target electrode. A target extender electrode may be between the suppressor electrode and the target electrode and have an opening therein to permit passage of charged particles to the target. At least one voltage source may be coupled to the target electrode, the suppressor electrode, and the target extender electrode to cause the target electrode to have a voltage greater than a voltage of the suppressor electrode and to cause the target extender electrode to have a voltage greater than the voltage of the suppressor electrode.Type: GrantFiled: September 16, 2012Date of Patent: February 16, 2016Assignee: Schlumberger Technology CorporationInventors: Frederic Gicquel, Kenneth E.

Patent number: 9053893Abstract: A radiation generator includes an insulator, with an ion source carried within the insulator and configured to generate ions and indirectly generate undesirable particles. An extractor electrode is carried within the insulator downstream of the ion source and has a first potential. An intermediate electrode is carried within the insulator downstream of the extractor electrode at a ground potential and is shaped to capture the undesirable conductive particles. In addition, a suppressor electrode is carried within the insulator downstream of the intermediate electrode and has a second potential opposite in sign to the first potential. A target is carried within the insulator downstream of the suppressor electrode. The extractor electrode and the suppressor electrode have a voltage therebetween such that an electric field generated in the insulator accelerates the ions generated by the ion source toward the target.Type: GrantFiled: March 14, 2013Date of Patent: June 9, 2015Assignee: Schlumberger Technology CorporationInventors: Jani Reijonen, Frederic Gicquel, Joel L. Groves, Peter Wraight, Kenneth E. Stephenson

Patent number: 8000447Abstract: A gamma ray generator includes an ion source in a first chamber. A second chamber is configured co-axially around the first chamber at a lower second pressure. Co-axially arranged plasma apertures separate the two chambers and provide for restricted passage of ions and gas from the first to the second chamber. The second chamber is formed by a puller electrode having at least one long channel aperture to draw ions from the first chamber when the puller electrode is subject to an appropriate applied potential. A plurality of electrodes rings in the third chamber in third pressure co-axially surround the puller electrode and have at least one channel corresponding to the at least one puller electrode aperture and plasma aperture. The electrode rings increase the energy of the ions to a selected energy in stages in passing between successive pairs of the electrodes by application of an accelerating voltage to the successive pairs of accelerator electrodes.Type: GrantFiled: July 30, 2009Date of Patent: August 16, 2011Assignee: The Regents of the University of CaliforniaInventors: Jani Petteri Reijonen, Frederic Gicquel
