steps to full IFO |
|
|
In moving now to full IFO locking, there are a number of sub-states to diagnose:
- PRMI + 1 arm
- Measure sensing matrix as arm is scanned into resonance. Compare time series of sensing matrix elements with New LoopTickle simulation. But first, we need more than 1 LOCKIN screen in the LSC! That will allow us to measure all of the elements of
simulataneously.
- Measure 3f PRMI noise spectra as a function of arm position. Look for trouble.
- DRMI + 1 arm
- Same as PRMI above.
- Want to find why this is unstable sometimes. Make stable for t > 10 minutes.
- Maybe add some QPD->ASC for SRC angular control, but how? Will this still work after the arms are resonant or will it be swamped by carrier contrast defect? Will Berlusconi ruin all of the Italian gelateria? Only time can tell...
- FPMI (non optically recombined) for ALS diagnosis
- PRFPMI (iLIGO configuration)
- this ought to be easier than DRFPMI
- will let us tell if our ALS is good enough to handle the coupled cavity pole
- DRFPMI (aLIGO style)
Which to do first and in what order? |
