Magnet Projects
Engineer Andy Rubes machines an instrumentation rotator for a magnet probe.
In addition to working on magnet projects for the lab, MS&T cooperates with industry and other laboratories on a variety of magnet technology projects. These projects cover the range of analysis, design, materials, component development and testing, coil fabrication, cryogenics, system integration and testing.
Our scientists and engineers are involved in the following special projects and MS&T-built user magnets.
Special Projects
Korea Basic Science Institute
In 2005, the Korea Basic Science Institute, located in Daejeon, South Korea, and the Mag Lab opened the doors to the KBSI-NHMFL Research Collaboration Center. The goal of the center is to promote basic scientific research, create knowledge and new opportunities for revolutionary technologies, and undertake development of new magnet systems for chemistry, biology and other fields of science and engineering. The first major initiative is a next-generation 21 tesla ICR superconducting magnet system that would provide a 45 percent increase in magnetic field over the current world-record 14.5 tesla Fourier transform ICR instrument at the Mag Lab. Future projects include the development of an unprecedented 1.1 to 1.3 GHz (approximately 25 to 30 tesla) Nuclear Magnetic Resonance superconducting magnet system. Read more.
Series Connected Hybrid for the Magnet Lab
In 2006, the National Science Foundation awarded the lab an $11.7 million grant for construction of a cylindrical-bore Series-Connected Hybrid (SCH), for high field nuclear magnetic resonance (NMR), condensed matter physics, biology and chemistry, to be located at the Magnet Lab’s Tallahassee location.
Series Connected Hybrid for the Helmholtz Centre Berlin
In 2007, the Helmholtz Centre Berlin (then known as the Hahn-Meitner Institute) contracted with the Mag Lab to build an $8.7-million SCH magnet for neutron scattering experiments.
Series Connected Hybrid for the Spallation Neutron Source
In 2006, the Magnet Lab was granted a design contract to build a split-gap Series-Connected Hybrid magnet for the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory.
Split Florida Helix
In 2007, Mag Lab Engineers successfully tested a groundbreaking new magnet design that will have the ability to direct and scatter laser light at the sample not only down the bore, but also from four ports on the side of the magnet. Engineers expect the 25-tesla magnet will be operational in 2010.
User Magnets
45 T Hybrid Magnet
The 45 T hybrid magnet was designed as a versatile, reliable, user-friendly magnet system capable of producing 45 T in a 32 mm bore. The system consists of two sets of coils: the superconducting outsert and the resistive insert. The outsert contains three concentric cable-in-conduit coils operating at 1.8 K. The resistive insert contains five water-cooled Florida-Bitter coils. The system was originally designed for the outsert to provide 14.2 T and the insert to provide 30.8 T, for a total of 45 T.
900 MHz Magnet
The 900 MHz magnet is a very wide bore high resolution NMR magnet, with a central field of
21.1 T, a room temperature bore of 100 mm, and a temporal and spatial homogeneity objective of less than 1 part per billion in a 4 cm DSV. It is a major part of the long-term goal of achieving high resolution at 25 T, corresponding to a proton resonance frequency of 1.066 GHz. The future 25 T magnet will consist of a high temperature superconducting (HTS) inner coil operating in the field of a large low temperature superconducting (LTS) outer magnet.
Pulsed Magnets
The objective of the pulsed projects, housed at the lab's Pulsed Field Facility at Los Alamos National Laboratory, is to develop and improve magnet technology to produce pulse coils that sustain physics research operations at the facility. We upgrade user magnet performance as we develop reliable improvements in technology. Currently, these projects include the 100 T, currently operating at 89 T, and the 60 T long-pulse. For more information about the pulsed magnet program, contact Chuck Swenson.
Resistive Magnets
The lab designs, builds and maintains high- field DC magnets for the scientific user community. The scope of activity ranges from hybrid inserts providing fields up to 45 T and consuming up to 30 MW of power to small, wire-wound coils that are inserted in the bore of high field magnets. The scientific community to whom we provide service consists primarily of the users of DC field facility, but we also provide contract services to facilities in Tsukuba, Japan and Nijmegen, the Netherlands, among others.
