40m work plan

This should be kept up-to-date. This is an overview of our near-term goals. We can link to other TODO lists from here.

PRMI commissioning

• PRMI locked!
• Investigate triggering (trigger on POP110 instead?)
• What is the correct normalization?
• Lower Q on Vio2 filters
• Finish updating IFO configure scripts, medm "restore" (Jamie)
• OSA modulation depth measurements at:
  • REFL
  • AS
• Power budget at all available ports, include 1f(22)/2f(110)
  • PRC gain

• Oplev calibration (BS? PRM?)

• Sensing matrix
• Cavity length (use new Anamaria method)
• Loop gain (make sure loop is stable for measurements)
• Noise budget
• Full Finesse model.
• Fix hardware anti-aliasing in LSC (move up cutoff freq to correspond to sample rate)

DRMI

This and FPMI are the next primary tasks. We will need to vent to flip SR2 first, although we need better calculation of the PRC/SRC coupled-cavity affect on the SRC mode.

• SRC mirror RoC calculations. What is the long-term solution? (Jamie)

End table upgrade

This is needed before we move on the FPMI commissioning.

• Project page

• ETMY table must be completed ASAP (Manasa)
  • What is left to do?
• ETMX upgrade needs to be planned/coordinated.

FPMI

We obviously need both end tables fully functional before we get to this.

PRFPMI

• Oplev calibration for ETMX, ETMY

DRFPMI

Next vent

Will need to vent soon to flip SR2.

• SR2 flip
• Are all black glass beam dumps installed?

Longer term:

• New OSEM mount screws
• New periscope plate
