Fringe Mover - NanoBPM

Instructions for using Honda's Fringe Based Mover System

1) ssh to his machine... ssh nanobpm@atfnbpm-1.atf-local (sakaihiroshi)

2) setenv DISPLAY xxx:0.0 (where xxx is your machine)

3) cd /home/nbpm/DAQ/OI/

4) ./fringe_mover

5) to view scopes via webcam, go to:

Mover for downstream BPM isn't working properly... can reset it at the crate in the eel's bedroom if something goes wrong.
The piezo movers are numbered as upstream=3, downstream=2, center=1 in the moversystem HV. In the feedback part, they are set up as upstream=upper-left, downstream=upper-right, center=lower-left. The small on/off switch can be used to reset.

Once you have the mover controls up (using fringe_mover), BPM#1 = upstream BPM, BPM#2 = center, and BPM#3 = downstream. In his system system, 1 step=316nm (2 steps=628nm, which is the max you can go). You should press reset first to zero everything, and you can watch the webcam to view the scope traces of the voltages for the piezo movers. (You'll see that BPM#3 mover doesn't really work.)
