Download or read book Design Status of the US 100 Tesla Non-destructive Magnet System written by and published by . This book was released on 1996 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collaborative effort is now underway in the US between the Department of Energy and the National Science Foundation to design, build, and use a 100 T non-destructive magnet for studying the properties of materials at high fields. The National High Magnetic Field Laboratory (NHMFL) at Tallahassee, Florida, and Los Alamos, New Mexico, where the magnet will be sited, is carrying out this task. This magnet will join other pulsed magnets at NHMFL, to provide magnetic fields at strengths, time durations, and volumes that are longer (in combination) than any now available. In particular, the goal for the 100 T magnet is a time duration above 80 T of about 15 ms in a cold bore of 24 mm. The present status of the design effort and various design issues are presented here.

Book excerpt: Scientists at the Los Alamos National Laboratory campus of the National High Magnetic Field Laboratory have successfully produced the world's first 100 Tesla non-destructive magnetic field. The achievement was decades in the making, involving a diverse team of scientists and engineers. The 100 Tesla mark was reached at approximately 3:30 p.m. on March 22, 2012. A note about the sound you'll hear when the magnet is energized: The sound that the 100 T multi-shot magnet makes is due to the electrical current modulation from the 3 phase power converters (known as 12 pulse converters) and the harmonics associated with the chopping of the sinusoidal input power. The magnet vibrates at the electrical current frequencies multiplied by 12 (i.e. ~ 55 Hz x 12 = 660 Hz) hence making an audible sound. The generator is not run at full speed (1650 RPM instead of 1800 RPM) so the frequency is slightly lower than US Line frequency (i.e. 55 Hz instead of 60 Hz). A spectrograph of the sound from the magnet pulse shows the multiple harmonics as reddish horizontal bands as a function of time.

Book Synopsis Completion of the US NHMFL 60 T Quasi-continuous Magnet by :
Download or read book Completion of the US NHMFL 60 T Quasi-continuous Magnet written by and published by . This book was released on 1997 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a technical summary report of the 60 T controlled power research magnet that was designed, assembled, installed and recently commissioned at the National High Magnetic Field Laboratory (NHMFL) Pulsed Field Facility at Los Alamos National Laboratory. The magnet is a innovative in its design, construction, size, operation and power supply. The magnet consists of nine nested, mechanically independent, free standing coils, each of which is enclosed by a steel reinforcing shell. Using inertial energy storage a synchronous motor-generator provides ac power to a set of five ac-dc converters rated at 64 MW/87.6 MVA each. These converters energize three independent coil circuits to create 90 MJ of field energy at the maximum field of 60 T, which can be sustained for 100 ms in the 32 mm bore. Prior to a pulse the 4-ton magnet is cooled to liquid nitrogen temperature, a procedure that is achieved in less than one hour by the free flow of nitrogen between the nine coils. In addition to being the most powerful of its class in the world the magnet is also the first of its kind in the US. The operation of the magnet will be described along with special features of its design and construction. A sampling of the pulse shapes that can be obtained for research will be shown.

Download or read book The U.S. NHMFL 60 T Long Pulse Magnet Failure written by and published by . This book was released on 2001 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 60 T long pulse magnet operated by the U.S. National High Magnetic Field Laboratory at Los Alamos National Laboratory, Los Alamos, New Mexico failed catastrophically on July 28, 2000. The failure was investigated and the cause was determined to be unusually low toughness in the nitrogen strengthened manganese stainless steel (Nitronic-40) reinforcing material. The source of the reduced toughness condition was a sigma phase conversion in the microstructure. The magnet failure, failure investigation and results of the investigation are described. Plans for the construction of the successor magnet, the 60 tesla long pulse Mark II, are described.

Book excerpt: High-field magnetsâ€"those that operate at the limits of the mechanical and/or electromagnetic properties of their structural materialsâ€"are used as research tools in a variety of scientific disciplines. The study of high magnetic fields themselves is also important in many areas such as astrophysics. Because of their importance in scientific research and the possibility of new breakthroughs, the National Science Foundation asked the National Research Council to assess the current state of and future prospects for high-field science and technology in the United States. This report presents the results of that assessment. It focuses on scientific and technological challenges and opportunities, and not on specific program activities. The report provides findings and recommendations about important research directions, the relative strength of U.S. efforts compared to other countries, and ways in which the program can operate more effectively.

This book was released on 2013-12-25 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Committee to Assess the Current Status and Future Direction of High Magnetic Field Science in the United States was convened by the National Research Council in response to a request by the National Science Foundation. This report answers three questions: (1) What is the current state of high-field magnet science, engineering, and technology in the United States, and are there any conspicuous needs to be addressed? (2) What are the current science drivers and which scientific opportunities and challenges can be anticipated over the next ten years? (3) What are the principal existing and planned high magnetic field facilities outside of the United States, what roles have U.S. high field magnet development efforts played in developing those facilities, and what potentials exist for further international collaboration in this area? A magnetic field is produced by an electrical current in a metal coil. This current exerts an expansive force on the coil, and a magnetic field is "high" if it challenges the strength and current-carrying capacity of the materials that create the field. Although lower magnetic fields can be achieved using commercially available magnets, research in the highest achievable fields has been, and will continue to be, most often performed in large research centers that possess the materials and systems know-how for forefront research. Only a few high field centers exist around the world; in the United States, the principal center is the National High Magnetic Field Laboratory (NHMFL). High Magnetic Field Science and Its Application in the United States considers continued support for a centralized high-field facility such as NHFML to be the highest priority. This report contains a recommendation for the funding and siting of several new high field nuclear magnetic resonance magnets at user facilities in different regions of the United States. Continued advancement in high-magnetic field science requires substantial investments in magnets with enhanced capabilities. High Magnetic Field Science and Its Application in the United States contains recommendations for the further development of all-superconducting, hybrid, and higher field pulsed magnets that meet ambitious but achievable goals.
