Abstract
An optical gaussmeter for determining the magnitude and homogeneity of the magnetic field in the core of a superconducting magnet includes a crystal of calcium fluoride doped with divalent thulium disposed in the core of the magnet. The crystal is exposed to RF radiation and to a narrow beam of light filtered to a wavelength corresponding to the absorption band of the divalent thulium in the crystal. The light beam signal as altered by the absorption characteristics of the crystal corresponds to the measured magnet current which manifests the field magnitude to be determined.
