Pulsed magnetic field measurement system based on colossal magnetoresistance B-scalar sensors for railgun investigation

A high pulsed magnetic field measurement system based on the use of CMR-B-scalar sensors was developed for the investigations of the electrodynamic processes in electromagnetic launchers ...

The system was tested using the electromagnetic railgun RAFIRA installed at the French-German Research Institute of Saint-Louis, France.

Diagnostic Capabilities for Electromagnetic Railguns

...This paper will describe results from Georgia Tech and Navy efforts to evaluate diagnostic techniques that measure different phenomenon at higher resolution in both time and space in order to provide the data needed to validate railgun models... Examples of electromagnetic sensors that will be presented include colossal magneto-resistance (CMR) sensors, which respond to changes in a magnetic field with a change in resistance...
