I have done a quick update of the IFO_ALIGN screen's save and restore scripts, so that we can now also save, restore, and view the saved values for
the input tip tilts.
In the past, there was an "if" statement to check if the optic was a PZT, and if so, define the alignment channels accordingly (since |

Interesting. It seems for me that there is a dependence of the noisiness as the beat frequency is
scanned.
As you increase (or decrease?) the offset, C1:ALS-BEATY-COARSE_I_IN1 becomes bigger and more crisp. |

Is that time stamp really correct? I wanted to look at the signal closely to see if I could get any feeling for why it would look so different
when positive vs. negative, but I do not see a triangle anywhere near this time (1023780144)...

In pursuit of a low back scattering, high power beam dump we looked at materials such:
polished copper, polished aluminum, diamond cut aluminum, variety of polished & heat treated stainless steel and shades of black glasses.
Black glass is ideal at low power. Superpolished SS 304 #8 is the only material that measures close to bg
