National High Magnetic Field Laboratory (NHMFL) 900 MHz NMR Probe |
Sponsor and Advisor Information |
The group is being sponsored by the National High Magnetic Field Laboratory (NHMFL) Nuclear Magnetic Resonance (NMR) Facility. The liaison engineers that will be assisting and advising for the duration of the project are Dr. William Brey and Peter Gor’kov. The NMR Facility researches and fabricates many different types of hardware for NHMFL research. Current projects consist of: Development of Probes for 900 MHz Ultra-Wide Bore (UWB), HTS Probe for Natural Products, Low-E Probes for Biological Solid-State NMR, 29 mm Family of Narrow Probes for High Field 830 MHz and Resistive Magnets, and NMR in Resistive and Hybrid Magnets.

Dr. William Brey |
He came to the NHMFL in 1999. Prior to joining the NMR group, Brey had primary responsibility for RF coil design for the Conductus/Varian team that developed the superconductive NMR spectroscopy probe. His graduate work with Thomas Mareci and Raymond Andrew at the University of Florida included the development of new designs for gradient coils. Before his graduate study, Brey worked on the research staff at the University of Texas Health Sciences Center, Houston, where he developed pulse sequences, gradient, and RF hardware for MRI and MR spectroscopy. He also worked as a consulting engineer for Tecmag, Inc., which produces retrofit hardware upgrades for NMR spectrometers. At the NHMFL Brey has continued his work with superconductive probes, guided the commissioning of the 900 MHz ultra-wide bore magnet, and is now developing probes and related technology for NMR on the Series Connected Hybrid magnet that is under development. |
He came to NHMFL in 1999 from the group of Paul Lauterbur at the University of Illinois in Urbana-Champaign where he designed MRI probes for small animal MRI. At the NHMFL, Gor'kov has designed and built over 25 user probes and accessories for solid state NMR in superconducting and resistive magnets, including RF probes for the 900 MHz UWB magnet. While other labs have acquired high field NMR magnets, the strength of the Magnet Lab's NMR program rests in large part on providing users with unique RF probes that are not available elsewhere. Peter's recent interests focus on developing instrumentation for NMR of biological solids to aid with solving structure of insoluble proteins in a native environment. Gor'kov has come up with several user RF probes that use specially designed low-E resonators instead of conventional solenoids to minimize the high-frequency electric fields that heat protein samples. This allows users to perform sensitive biological NMR experiments in the high field 900 MHz magnet. Several such probes were built for use at other facilities, including Pacific Northwest National Laboratory and Karlsuhe Institute of Technology. |
Prior to joining Florida State University, Dr. Van Sciver was Research Scientist and then Professor of Nuclear Engineering, Engineering Physics and Mechanical Engineering at the University of Wisconsin-Madison from 1979 to 1991. He was also Associate Director of the Applied Superconductivity Center. Dr. Van Sciver received his PhD in Low Temperature Physics from the University of Washington-Seattle in 1976. |
He is a Distinguished Research Professor in Mechanical Engineering and Director of Magnet Science and Technology at the National High Magnetic Field Laboratory (NHMFL). He joined the FAMU-FSU College of Engineering and the NHMFL in 1991, initiating and teaching in the graduate program in Magnet and Materials Engineering and in cryogenic thermal sciences and heat transfer. Dr. Van Sciver was previously the Director of Magnetic Science and Technology at the NHMFL. In this capacity he manages the group of about 70 professional staff and students that develop high field magnet systems for the NHMFL. Dr. Van Sciver is a Fellow of the ASME and the American editor for the journal Cryogenics. |
