Reference Laser

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()
