Mirror M0 (LBL mirror)

This mirror has motorized adjustments for mir_yaw which deflects the beam horizontally and mir_roll which deflects the beam vertically (see Fig. 3.4), and mir_x (Fig. 3.5) which moves the mirror assembly inboard or outboard. The When adjusting the position of mirror M0 (the LBL mirror), please measure the mirror's position with a caliper as is shown in Fig. 3.5.

Figure 3.5: The mir_x motor (left) moves the M0 mirror into and out of the beam in the inboard/outboard direction. The place where reference positions are read with a micrometer is shown at right.
