National High Magnetic Field Laboratory
Senior Superconducting Magnet Systems Engineer
Scott Marshall is an engineer with 28 years experience designing and building devices and systems enabled by high-temperature superconductors. He has mechanical engineering degrees from Georgia Tech (BME 1987) and Florida State University (MSME 1992). He started his career in superconductivity in 1994 as part of the team that developed and built the 900 MHz NMR magnet for the National High Magnetic Field Laboratory (MagLab) with responsibility for the mechanical design and process development for the Nb3Sn layer wound solenoids. From 2001-2005, he worked with the MagLab at Los Alamos to develop the 65 Tesla pulsed magnet. The effort enabled a 5 Tesla increase in field from 60 Tesla and an operational lifetime from 1000 to 10000 cycles. From 2005-2011 he worked with a small company managing SBIR projects with NASA to provide HTS magnets for the VASIMR plasma thruster. He secured ~$1.5M in Phase 1 and Phase 2 SBIR funds to develop a quick disconnect fitting for an HTS degaussing cable for the US Navy. The work was patented and then licensed to American Superconductor and subsequently resulted in four contracts for installation on Navy warships now under construction.
He rejoined the Magnet Lab in 2011 to support the construction of three Nb3Sn cable-in-conduit magnets for the Helmholtz Zentrum Berlin, the High Field Magnet Laboratory at Radboud University, Nijmegen, the Netherlands and for the Series-Connected Hybrid magnet at the NHMFL. He was responsible for the design and construction of the 20 kA HTS current leads for the Nijmegen and MagLab magnets. Presently he is supporting the 40 T superconducting magnet project at the MagLab working to improve methods of joining REBCO conductors and for development of coil fabrication processes.
Panel Session: The future outlook for medical magnetic resonance imaging superconducting magnets enabled by new materials
New superconducting materials are constantly emerging as the entire world is pushing hard to discover, integrate and scale up superconducting magnet systems for medical magnetic resonance imaging (MRI) machines. These new materials hold the promise of enabling helium-free MRI systems with potentially lower costs to manufacture and operate with increased reliability and resiliency.
The MRI research and development space is a unique field where the intersection of materials science and magnet technology are leveraged in tandem to produce a medical imaging solution that is simply unrivaled by other imaging technologies like X-rays, ultrasound and computerized tomography. Because the imaging quality and utility of MRI is the best amongst all other options, continual improvement in this field has the potential for very significant commercial disruption and economic gains in a rapidly increasing global market.
