keyword=Beam position on BeO
Established beam position with BeO:
When in 0,0 for both BPMs A and B, we saw a spot at the lower right side of the camara. When in the original position, A (-1.5,0), B (_3.5,2),we did not see the spot. Changed to 0, 0 again then slowly move. Eventually back to the orginal spot, it wentto the center and then could not see it (the center of the BeO got burned off probably.
