A Mole for Measuring Pulsed Superconducting Magnets

The facility for antiproton and ion research (FAIR) at Gesellschaft fur Schwerionenforschung (GSI) will build two superconducting synchrotrons requiring fields of up to up to 2 T at 4 T/s (SIS 100) and 6 Tesla at 1 T/s (SIS 300). The magnets of these rings will be measured using a mole which is currently under development. The main component of the field must be measured with a precision of 250 ppm and the higher order harmonics with a precision better than 100 ppm for DC and pulsed operation. This paper is focused on the pulse measurement using the "step by step" method.
