Patent number: 10107923Abstract: A receiving container for a detector which operates in an ultrahigh vacuum or in a protective gas atmosphere that consists of high-purity gas. The receiving container has a receiving portion which forms at least a portion of the receiving space for the detector, and a cover for hermetically sealing the receiving space. A first sealing surface is arranged at the receiving portion and a second sealing surface matching the first sealing surface is arranged at the cover. Between the sealing surfaces a gasket is arranged. A securing device presses the cover against the receiving portion to provide a defined contact pressure of the gasket.Type: GrantFiled: November 20, 2015Date of Patent: October 23, 2018Assignees: Universität zu Köln, Canberra FranceInventors: Peter Reiter, Jürgen Eberth, Herbert Hess, Stefan Thiel, Benoit Pirard, Jean Clauss, Louis Delorenzi, Marie Odile Lampert

Patent number: 9547093Abstract: A radiation camera system and method incorporating a radiation sensor/detector (RSD) and automated operation of coded camera aperture masks (CAMs) is disclosed that may be advantageously applied to real-time tracking of radiological hot spots in crisis, maintenance, decontamination, and/or maintenance scenarios. The system/method integrates automated camera RSD positioning, CAM identification, and CAM rotation. The system incorporates computerized controls in conjunction with remotely controlled horizontal/vertical tilting motors to direct the RSD aperture position and view of the RSD. CAMs may be installed in the camera manually and are automatically identified by the system via the use of encoding magnets that are detected using a Hall-effect sensor. The CAMs may be rotated after installation in the camera by computer control to predefined positions such as “mask” and “anti-mask” to affect the desired degree of radiation screening to be applied to the RSD.Type: GrantFiled: November 19, 2014Date of Patent: January 17, 2017Assignee: CANBERRA FRANCE SASInventors: Daniel De Toro, Nabil Menaa, Roger Abou-Khalil, Philippe Talent, Florent Bonnet, Audrey Patoz, Christian Duloisy, Khalil Amgarou

Publication number: 20160011320Abstract: A radiation probe system and method incorporating adaptive gamma radiation background subtraction for enhanced radiation detection capability is disclosed. The system and method are generally applicable to radiation “frisking” applications in which the contamination area may have high gamma radiation background levels that normally would result in loss of contamination radiation detection accuracy. Readings from a background radiation detector (BRD) are subtracted from a contamination radiation detector (CRD) to determine a count rate solely associated with contamination. A background subtraction factor (BSF) is used to scale the BRD subtraction and is automatically adjusted based on environmental conditions. A smoothing algorithm is used to increase/decrease the BRD and/or CRD acquisition times to account for signal variations in BRD/CRD measurement readings. The system and method provide for lower limit of detection (LLD) radiation levels that are below that of conventional radiation detectors.Type: ApplicationFiled: March 2, 2015Publication date: January 14, 2016Applicant: Canberra France SASInventors: Archibald Dupont, Adrien Gallozzi Ulmann, Frédéric Meyer, Nabil Menaa, Xavier Ducoux

Patent number: 8754377Abstract: A radiation detector system/method implementing a corrected energy response detector is disclosed. The system incorporates charged (typically tungsten impregnated) injection molded plastic that may be formed into arbitrary detector configurations to affect radiation detection and dose rate functionality at a drastically reduced cost compared to the prior art, while simultaneously permitting the radiation detectors to compensate for radiation intensity and provide accurate radiation dose rate measurements. Various preferred system embodiments include configurations in which the energy response of the detector is nominally isotropic, allowing the detector to be utilized within a wide range of application orientations. The method incorporates utilization of a radiation detector so configured to compensate for radiation counts and generate accurate radiation dosing rate measurements.Type: GrantFiled: April 23, 2012Date of Patent: June 17, 2014Assignee: Canberra France SASInventor: Olivier Gaëtan Giarmana
