Two upstream reference lasers can be used to provide rough beam position and direction to help with alignment: one on SB1 (in the SXR hutch) and the other on SB2 in the time tool chamber assembly. They are both green, propagating colinear with the X-ray path.
SB1 reflaser:
reflaser.movein()
reflaser.moveout()
in xpphome:
reference laser motors are under "Filter" or first grey motors in the left on, under SB1 section. Pic03 and Pic04 are translation stages to move the laser (units between 1 and 10 are ok), Pic01 and Pic02 are rotations to move the laser a considerable amount in downstream (units of 0.020 degrees are ok)
the filter wheel will adjust the intensity of the laser.
TT reflaser:
m.tt_y.mv_out()
m.tt_y.mv_reflaserPink()
