The first magnets using High Temperature Superconductors to operate at higher field than Nb-based superconductors have only recently been put into service. Most prominent among them are the 1.2 GHz (28.2 T) NMR magnets delivered by Bruker in 2020 and the 32 T magnet for condensed matter research that met specification in 2017. This webinar will address possibilities for higher field magnets for neutron scattering, focusing on the possibilities opened up by the high temperature superconductors but also touching on dc and pulsed resistive magnets.
Dr Mark D. Bird, Director of MS&T
Dr. Bird completed his PhD in mechanical Engineering at Stanford University in 1992. He then joined the National High Magnetic Field Laboratory (MagLab) where he led the development of a number of resistive magnets for condensed matter physics experiments before becoming the Director of the MagLab's Magnet Science and Technology Division in 2006. As such he is responsible for the development of dc magnets for the MagLab. The MS&T division also assists in the development of pulsed magnets for the MagLab's pulsed field facility, particularly focusing on developing better high-strength high-conductivity alloys and fabrication of the larger coils.
Since 2006 MS&T has delivered a 25 T split magnet for visible optics and far infrared experiments; a 26 T magnet for neutron scattering at the Helmholtz Zentrum Berlin (HZB); a 36 T, 1 ppm magnet for solid state NMR; a 41.5 T resistive magnet; a 32 T all-superconducting magnet; and the superconducting coil for a 45 T magnet at the Nijmegen magnet lab. MS&T's main development effort presently is a 40 T all-superconducting magnet.Dr. Bird also serves on the Global High Field Forum, a consortium of high field magnet labs worldwide and is a member of the board of directors of Florida State University Magnet Research & Development, Inc, a non-profit organization that developed the 26 T neutron scattering magnet at HZB as well as the superconducting coil for the Nijmegen magnet lab.
