Bending Fine

Usually the bending-fine current is between 4 and 6% of the bending-course current. Large discrepancies of bending fine relation for the photon energies can introduce a shift in focal position. A shift in focal position will result in problems with light-xray field alignment in the GT direction.

Use TSD (Test Shelter Docs) procedures for correct BF/2R setup.

For electrons: Tune for max dose rate. (start with 2R at min. leakage).
