X25 Undulator Magnet Measurements

Magnetic measurements of undulator was complete by January 2005

Considering shimming actuators

The magnetic field in the assembled undulator was measured with a scanning Hall probe along several beam-parallel tracks. Mechanical shims were added to gap actuators to achieve the design field uniformity.
