Abstract :
A versatile field measurement system HAL2 was developed and used for SSC magnet measurements. The system based on V/F converter and 32 bit counters are set on a VME/modified VME bus. The system was capable of measuring the high ramp rate harmonics which was a vital issue especially for the construction of SSC High Energy Booster. System description and the implementation techniques for high ramp rate application is presented together with the measurement data in SSC dipole model magnet. The measurement up to 128 A/s was successful. Anomaly in the eddy current quadrupole was clearly observed
