A measurement system for the detection of small magnetic flux changes in superconducting magnets, which are due to either mechanical motion of the conductor or flux jump, has been developed at Fermilab. These flux changes are detected as small amplitude, short duration voltage spikes, which are /spl sim/15 mV in magnitude and lasts for /spl sim/30 /spl mu/sec. The detection system combines an analog circuit for the signal conditioning of two coil segments and a fast data acquisition system for… CONTINUE READING
