Abstract :
Efficient analytical methods for the determination of the shims were established. The calibration of the probes is detailed and the shimming method is summarized. As a final verification, results with real beam are shown. A beam with nominal emittance was conducted up to the focal plane of the spectrograph. A full width at half maximum of 0.26 mm was obtained, corresponding to a resolution of 3.2*10-5, in good agreement with the expected value.
