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