X25 Undulator Magnet Shimming

Shimming and measurements of undulator magnet structure was completed by Dec 2005

Close up of pulsed wire probe
First wire probe measurements
Shimming of full assembly

Beam trajectory measurents with a pulsed wire probe were used to evaluate and test magnetic shims that make the average filed uniform along each magnet array.
