Patent number: 10139496Abstract: A multi-radiation identification and dosimetry system and method that allows for monitoring of alpha, beta, and gamma radiation is disclosed. The system/method incorporates a segmented silicon drift detector (SSDD) that allows measurement of directly absorbed radiation in the semiconductor (betas, conversion electrons, Lx lines, and alphas) on one SSDD segment and radiation from a radiation scintillation detector (RSD) on multiple segments of the SSDD. With the anode side of the SSDD directed toward the radiation inspection surface (RIS), the SSDD+RSD stacked radiation detector collects radiation which is processed by a charge sensitive amplifier (CSA) and then processed by a time stamping differentiator (TSD). A computing control device (CCD) may be configured to collect the time stamp differentiation data from the various SSDD segments to permit the simultaneous discrimination of several types of radiation by and presentation of these radiation types and counts on a display monitor.Type: GrantFiled: December 9, 2015Date of Patent: November 27, 2018Assignee: MIRION TECHNOLOGIES (CANBERRA), INC.Inventors: Olivier Roger Evrard, Roger Abou-Khalil, Stephane Dogny, Nabil Menaa, Wilhelm Friedrich Mueller, Mathieu Morelle, Edward Lee Reagan

Publication number: 20120186317Abstract: A finishing rolling device for manufacturing a thin magnesium strip based on a coil fed to the device includes a roll stand for accommodating at least two working rolls (32, 33) that define a roll gap. A first coiler accommodates the coil and feeds the magnesium strip to the roll gap and a second coiler for winding up the magnesium strip after it passes through the roll gap. The first coiler is provided with a heating device and a hood arrangement that shields the coil or the magnesium strip against heat radiation. The hood arrangement of the first coiler features a coil passage opening for introducing the coil into the hood arrangement on its housing side that faces away from the roll stand.Type: ApplicationFiled: December 16, 2011Publication date: July 26, 2012Inventors: Axel Barten, Werner Latzel, Wilhelm Friedrich Sommer, Thomas Rücker, Axel Marx
