ZM6, OM1, OM2 (+OM3 by RyanC, +OMC by Rahul) Transfer Functions Are COMPLETED (In Prep For Vent)
SUMMARY: Transfer Functions COMPLETED for ZM6, OM1, & OM2. Leaving in DAMPED guardian state for vent. Will post matlab plots in a comment to this alog later.
Joined team of others (Ibrahim, Jeff, Rahul, RyanC) in getting SUSpension transfer functions in preparation for upcoming vent. We split up the work amongst us. I took on ZM6, OM1 and OM2.
7/18/24 Update NOTE: OM3 measured by Ryan C, OMC measured by Rahul. Their results are posted in a comments below!
Instructions for this work is at: https://awiki.ligo-wa.caltech.edu/wiki/Suspensions/OpsManual/TFs/DTT
For TODAY, this is what I did:
- Run the Transfer Function measurements (and saved the .xml files)
- Exported the data (& saved as .txt files)
- And Added + Committed these new files to the SVN
Here are the locations of the files noted above:
- ZM6: /ligo/svncommon/SusSVN/sus/trunk/HXDS/H1/ZM6/SAGM1/Data
- FILES: 2024-07-17_2100_H1SUSZM6_M1_WhiteNoise_[L, P, Y]_0p02to50Hz.xml
- OM1: /ligo/svncommon/SusSVN/sus/trunk/HTTS/H1/OM1/SAGM1/Data
- FILES: 2022-10-07_1800_H1SUSOM1_M1_WhiteNoise_[L, P, Y]_0p02to50Hz.xml
- OM2: /ligo/svncommon/SusSVN/sus/trunk/HXDS/H1/OM2/SAGM1/Data (not HTTS !! Although there is another OM2 folder under HTTS.)
- FILES: 2024-07-17_1900_H1SUSOM2_M1_WhiteNoise_[L, P, Y]_0p02to50Hz.xml
Will leave all of these SUSpensions in their DAMPING guardian state (vs ALIGNED).
I ran the first analysis code for the OMs.
Attached are the Matlab-generated plots for ZM6 (with measurements I ran yesterday).
(Ryan already made the plots for OM1 & OM2 which I measured yesterday--Thanks!)
I should note this was my first time running through this procedure for taking SUS transfer functions. I had a few issues which came up (mainly svn-related), but got through some of this yesterday with Jeff's help, and Erik helped me this morning with other svn issues, but for these issues, I opted to not run an SVN update since there was a note for a "conflict". So I skipped the svn steps for plotting.
The Latest H1SUSZM6_M1_ALL_TFs.pdf is now availible
If you want to know where this lives on the CDS machines it can be found here:
/ligo/svncommon/SusSVN/sus/trunk/HXDS/H1/ZM6/SAGM1/Results
I have taken the in-vacuum measurements for OMC (HAM6) and they look great - see screenshots attached below.
