Standard Undulator Segment Support Structure
Special Attention: 1. Shear deformation and compressive deformation 2. Material pairing / Bimetallic bending3. Four point support of girders 4. Four Motors, electronic gears 5. Forced girder guiding6. Precision measurement of gap / Motor feedback to ±1µm, avoiding Abbé errors
Gap MeasurementAccuracy ±1µm

For the 3 poles next to the end ‘End Poles’ For all other poles ‘Bulk Poles’ Tuning done at the ‘Tuning Gap’:
U40: 14mmU68: 16 mm
Most Poles need to be tuned
One Tuning Step is (usually) sufficient
