On Figure 4.8 below, the two Beam Crossing Cells support is shown. To do a fine adjustment
of the 2 beams, use a hexagonal key to screw or unscrew the top left screw (to adjust height of
beams ref 7 circled) and the bottom right screw (to adjust the lateral positioning of the beams ref 8

They are spring loaded to improve accuracy and keep in place the two sensors after adjustment.
