SCALAR CALIBRATION OF 3-D COIL SYSTEM

Aleš Zikmund – Pavel Ripka

   The scalar method was used for calibration of the 3-D coil system. The method is based on obtaining set of non-linear equations by using a sequence of the calibration current steps into the individual coils or into the combination of coils. The coil sensitivities and angle between the magnetic coils axes were calculated by numerical method. The estimated achievable uncertainty is 0.02 degrees for angle and 0.01% for coil constant. The developed method was tested during the calibration of the 2-meter coil system in Průhonice.
