For regulation and ripple studies of dc magnets, the essential parameters which must be known as a function of dc magnetization and/or frequency are the unit step time constant and impedance. An exact value for the unit steptime constant of a laminat

Switching magnets, for time sharing of beam lines, can be pulsed directly from the ac power line if it does not cause objectionable line voltage fluctuations (flicker). Switching circuits, which are less expensive and more reliable than conventional

The ring-magnet current of the 12.5 BeV Zero Gradient Synchrotron (ZGS) and the current of a magnet test fixture at Argonne National Laboratory (ANL) are monitored with precision, four-terminal resistors (shunts) of coaxial design. These shunts, desi
