• Operation of V.STAT magnet.
If the V.STAT magnet is moved in the direction of the a and
b arrows, the red, green and blue points move as shown
below.
• 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.
