Description

We have developed a novel type of magnetic compass based on a spinning Hall probe. It is used for determination of the magnetic field direction in the polarized He-3 target during the GEn experiment. This compass does not require prior calibration and has no problem with probe signal drift. Obtained accuracy is better than one milli radian. The compass concept and design will be presented.
