Magnetic Field Measurement Systems

ADC magnetic field measurement system is a sophisticated and sensitive machine for the measurement of magnetic fields in undulators (Planar, EPU, and Apple II), wigglers, and in-vacuum ID units. The magnetic fields are measured using 3 axis hall-effect probes, mounted orthogonally to a thin wand. The wand is mounted to a carriage that rides on vacuum air bearings. The base is granite. A flip coil is provided on two vertical towers with X, Y and Theta axes. Special software is provided to assist in homing, movement, and data collection.
