•Operation of BMC (Hexapole) magnet.
If the blue or red point does not converge with the other two points, perform following steps:
Move BMC magnet (a) to correct insufficient H.static convergence.
Rotate BMC magnet (b) to correct insufficient V.static convergence
In either case, repeat Beam Landing Adjustment.
