The Aesthetics of Constructing and Deconstructing the MagLab's Magnets: An Overview of the National High Magnetic Field Laboratory

The MagLab generates magnetic fields exceeding two million times the Earth’s magnetic field using exotic materials and home-developed magnet designs. This talk seeks to answer the question “Why would anyone want to do such a thing?”  We start by surveying the aesthetics and science of materials, from the flaking of obsidian to the fabrication of nano-composites necessary for the construction of the MagLab’s world-record magnets. The use of these magnets will then be illustrated by a few research highlights from the MagLab’s international user community on • MATERIALS: tweaking quantum phenomena using electrons in two-dimensional square lattices of copper and oxygen; ENERGY: analyzing nature’s most complex fluid by measuring the mass of 100,000 different molecules in a single drop of oil; and • LIFE: using sodium and quantum dots to revolutionize magnetic resonance imaging.  During the talk, we anticipate that jokes will be told.

Simon Y. Foo, Ph.D., is a tenured Professor at the Department of Electrical and Computer Engineering (ECE) at Florida A&M University and Florida State University. He is currently the ECE department Chair. His research contributions have been in the areas of computational intelligence and photovoltaics, particularly high-efficiency multi-junction III-V compound solar cells. He is currently working on perovskite-based polymer solar cells. Dr. Foo has authored or co-authored over 100 refereed technical papers and contributed to two book chapters. He has also graduated more than 30 MS and PhD students. He is the Principal Investigator of at least 20 funded research projects with total funding of over 3 million dollars. His primary research sponsors include the National Security Agency, National Science Foundation, U. S. Air Force, Boeing Aircraft Company, and the Florida Department of Transportation. He also serves as a technical advisor to Airbus in the area of fire detection in aircraft cargo bays. He has won several awards such as the "Engineering Research Awards" from the FAMU-FSU College of Engineering, Tau Beta Pi "Teacher of the Year" award, and "Best Paper" awards. He is a member of Eta Kappa Nu Electrical Engineering Honor Society.

  Greg Boebinger
Director 
National High Magnetic Field Laboratory
Dr. Gregory S. Boebinger received Bachelors Degrees in Physics, Electrical Engineering and Philosophy in 1981 from Purdue University. He studied one year at Cambridge University as a Churchill Fellow, after which he entered the Massachusetts Institute of Technology in Fall 1982, where he held Compton and Hertz Foundation Fellowships. His thesis research utilized high magnetic fields and ultra-low temperatures to study the fractional quantum Hall effect with Nobel Laureates Horst Stormer and Dan Tsui. The fractional quantum Hall states are many-electron collective states found in two-dimensional layers of electrons in the presence of strong magnetic fields. They exhibit features in common with both superconductivity and superfluidity; however, the fractional quantum Hall states are strikingly unique in that they exhibit fractional charge, that is, particle-like excitations that are composites of magnetic-field flux quanta and electrons, yet exhibit charges equal precisely to one-third of an electron charge. After receiving his Ph.D. in Spring 1986, Dr. Boebinger spent a year as a NATO Postdoctoral Fellow in Paris at the Ecole Normale Superieure studying other quantum behaviors of electrons in quantum wells.

In 1987, Dr. Boebinger joined the research staff at Bell Laboratories and established a unique pulsed magnetic field facility for physics research on semiconductors, f-electron compounds and superconductors in magnetic fields up to 60 teslas, more than one-million times the Earth’s magnetic field. For this research, he was named a Fellow of the American Physical Society in 1996.

In 1998, Dr. Boebinger became head of the pulsed magnet laboratory at Los Alamos National Laboratory, one of the three campuses of the National High Magnetic Field Laboratory (MagLab). In 2004, Dr. Boebinger moved to Florida State University to become director of the MagLab, with responsibility for all three campuses: the headquarters at Florida State University, the pulsed magnet laboratory at Los Alamos National Laboratory, and the ultra-low temperature and magnetic resonance imaging laboratories at the University of Florida. The MagLab is the world leading magnet laboratory, developing and operating high magnetic field facilities that more than 1600 scientists use annually for research in physics, biology, bioengineering, chemistry, geochemistry, biochemistry, materials science, and engineering. More information can be found on the MagLab’s website: nationalmaglab.org

Prof. Boebinger continues his own research on the high-temperature superconductors, using the intense magnetic fields to suppress superconductivity. The goal is to study the behavior of the samples in the absence of their high-temperature superconductivity, with the expectation that this behavior underpins the superconducting state.  A detailed understanding of the non-superconducting states might well lead to an eventual understanding of high-temperature superconductivity.

Prof. Boebinger is keenly interested in communicating science to the general public. His outreach has included commencement addresses, public lectures and demonstrations on levitation at Aspen’s Wheeler Opera House, at Bell Laboratories, Los Alamos, and the Getty Museum. He has appeared on the History Channel and Discovery Channel and has written articles for Physics Today and Scientific American. He has a special interest in the historical development of materials research and the interplay of the Arts and Sciences.
