About Us

GMW began operations in 1982, as principals, Hilton Glavish, Barry MacKinnon and Ian Walker, from the defunct New Zealand company ANAC set up in the San Francisco Bay Area to support their existing North American customers. The company quickly moved from solely Lab Electromagnets into instrumentation, getting into the Magnetic Resonance Imaging (MRI) business with the founding of Metrolab Technology in the mid 80’s. Accelerator Physics and MRI drove growth throughout the 80’s and into the 90’s, with the Superconducting Supercollider (SSC) cancellation in 1993 allowing the company to further diversify into additional markets.

Today, GMW are 20 people with co-founder Ian Walker now entering his 37th year at GMW and continuing to offer a very high level of support to our customers.   read more

Senis NVM-01 Nanovolt Amplifier for high sensitivity measurement of magnetic flux changes

The Senis NVM-01 Nanovolt Amplifier was developed for very high resolution measurements of the magnetic flux distribution in ion and electron beam magnets by digitizing and integrating the voltage signal from a moving wire or rotating coil in the working region of the magnet. The magnetic flux in the region of interest sampled by the wire or Coil can be measured very quickly compared to point-by-point magnetic field mapping.

By using purpose shaped Coils the NVM-01 can enable the…
