A ferromagnetic shim insert for NMR magnets – Towards an integrated gyrotron for DNP-NMR spectroscopy #DNPNMR

Bridge12 is currently developing an integrated THz system for NMR-DNP spectroscopy. The basic idea is to operate the gyrotron inside the NMR magnet, just above the NMR probe head, effectively eliminating the need of a second superconducting magnet. This article is about a ferroshim insert that we had to develop for this purpose.

In recent years high-field Dynamic Nuclear Polarization (DNP) enhanced NMR spectroscopy has gained significant interest. In high-field DNP-NMR experiments (⩾400 MHz 1H NMR, ⩾9.4 T) often a stand-alone gyrotron is used to generate high microwave/THz power to produce sufficiently high microwave induced B1e fields at the position of the NMR sample. These devices typically require a second, stand-alone superconducting magnet to operate. Here we present the design and realization of a ferroshim insert, to create two iso-centers inside a commercially available wide-bore NMR magnet. This work is part of a larger project to integrate a gyrotron into NMR magnets, effectively eliminating the need for a second, stand-alone superconducting magnet.

Open position at Bridge12: Microwave and THz Systems Scientist

We are again looking to expand our team. Check out our new job posting for a Microwave and Terahertz Scientist. Your specific role will include development of novel systems such as:

  • Traveling wave tubes (TWT) from E-band (71-76 GHz) up to 500 GHz
  • Gyrotron oscillators and amplifiers from W-Band (75-110 GHz) up to 500 GHz
  • Development of electron guns for vacuum electron devices
  • High-power, low-loss transmission line systems for microwave and terahertz propagation

New SBIR award to Bridge12 – NIH Funds Development of THz resonator for solid-state DNP-NMR Probes

Press Release

NIH Funds Development of THz resonator for solid-state DNP-NMR Probes

SBIR Grant Awarded to Bridge12 for Dynamic Nuclear Polarization


Framingham, Mass. – July 18th, 2013 – Bridge12 Technologies, a leading provider of terahertz (THz) technology for applications in science, medicine, security, and defense, announces it has received a National Institute of Health’s small business innovation research (SBIR) grant for the development of a THz resonator for solid-state DNP-NMR probes. Dynamic Nuclear Polarization (DNP) can increase the sensitivity of a NMR experiment by several orders of magnitude, accelerating experiments that typically require weeks to complete in minutes.


Nuclear magnetic resonance (NMR) spectroscopy is used broadly across many disciplines, such as analytical chemistry, structural biology or drug discovery and scientists that are using NMR are often challenged by the low sensitivity of NMR, which slows down research and increases research costs.

In recent years, Dynamic Nuclear Polarization (DNPhas proven to be vastly successful in increasing sensitivity in solid-

state NMR experiments, achieving enhancement factors of > 180 at 400 MHz (1Larmor Frequency) corresponding to a factor of 32,400 in time savings. In other words, an experiment that would otherwise run for three weeks can be performed in less than a minute. This significantly increased overall sensitivity accelerates experiments for analytical applications of NMR spectroscopy as well as the structural characterization of bio-macromolecules or pharmaceutical drug discovery.
