In a large installation, strategically located dosimeter-enabled tags can yield an accurate, real-time, 2D or 3D dose field map that can be used to enhance facility safety, security, and safeguards. The detector is able to generate alarms for both high and low radiation and for a high cumulative dose. The detector has a wide measurement range for gamma radiation - from 0.1 mSv/h to 8 Sv/h. A compact dosimeter has been incorporated in the ARG-US tags via an onboard universal asynchronous receiver/transmitter interface. In conjunction with global positioning system (GPS) tracking provided by TRANSCOM, the system can also monitor and track packages during transport. ARG-US utilizes sensors in the tags to continuously monitor the state of health of the packaging and promptly disseminates alarms to authorized users. Several ARG-US systems are in various stages of deployment and advanced testing across DOE sites. Department of Energy (DOE) Packaging and Certification Program to use in managing sensitive nuclear and radioactive materials. One such system, called ARG-US, has been developed by Argonne National Laboratory for the U.S. 20585 (United States)Īutomated monitoring and tracking of materials with radio frequency identification (RFID) technology can significantly improve both the operating efficiency of radiological facilities and the application of the ALARA (as low as reasonably achievable) principle in them.

(orig.)Īs well as contributing important results on B mesons (particles carrying the fifth - 'beauty' - quark), the ARGUS detector at DESY's DORIS II electron-positron storage ring also specializes in the third generation of weakly interacting particles (leptons), with data on about half a million examples of electron-positron collisions producing pairs of tau particles In particular the ARGUS measurements of CKM matrix elements opened up a new window on the Standard Model. More than 10 years of data taking has allowed ARGUS to contribute significantly to our understanding of beauty and charmed hadrons, Ï„ leptons, Î¥ mesons, γγ interactions and fragmentation processes. The impact of the ARGUS experiment to elementary particle physics is reviewed. A total luminosity of 520 inverse picobarns has been The study of quark and gluon mechanisms (fragmentation) has yielded valuable input for future experiments, while the first observations of new final states in photon-photon interactions have created much interest. The charm study has resulted in first observations of many charmed hadrons and decay modes. These comprise measurements of quark transitions (CKM matrix elements) in the decays of B mesons (containing the beauty quark), the determination of the properties of the tau lepton and its neutrino, as well as a measurement of the quark coupling constant. In particular, ARGUS has made valuable contributions to determination of many fundamental constants of the Standard Model. During those ten years a broad spectrum of physics has been covered, including weak decays of beauty and charm quarks and tau leptons, hadron spectroscopy, quark/gluon mechanisms, photon-photon interactions and particle searches. In May 1993 the decision was taken to stop further ARGUS running. ![]() ![]() ARGUS rolled into the beam in October 1982 and took data until October 1992. With a similar programme started by the CLEO collaboration at Cornell's CESR electron-positron collider, the resulting competition ensured good physics. The detector was conceived to investigate the physics of the beauty and charm quarks and the tau lepton at the upgraded DORIS II electronpositron storage ring. Later groups joined from IPP Canada, Kansas, Ljubljana, Karlsruhe, Erlangen/Nurnberg, Heidelberg (MPI) and Dresden. The ARGUS collaboration was formed in 1978 by groups from DESY, Dortmund, Heidelberg (IHEP), Lund, Moscow (ITEP), and South Carolina under the leadership of Walter Schmidt-Parzefall. Analysis and new results will continue for some time, but members of the group are already looking to new physics horizons. Last year the ARGUS experiment at DESY's DORIS electron-positron storage ring stopped taking data after ten years of fruitful physics. This paper discusses the mechanical and electronic design of this device and presents first results from its successful test operation yielding an impact parameter resolution of about 18 μm. Horisberger, R.Ī silicon microstrip vertex detector has been built as an upgrade to the ARGUS detector for increased precision and efficiency in the reconstruction of decay vertices.
