Shoshana, Michael, Oli, Arnaud

• Verified capacitive plate are wired correctly
• Verified the HOQI wiring, and found where we had a flip between HOQI A and B (we had plugged the cables the wrong way at the db9 input of the hoqi preamp).
• Shoshana made a new MEDM screen, see attached
• Michael calibrated the angular HOQI readout in um in the HOQI1_DIST filterbank
• Tested the picomotor in chamber, using the spare channel from SPI. The screen is accessible either from the sitemap->ISC->Picomotors->TCS Y CO2->PICO 8 (or directly from the CRS_OVERVIEW screen)
  • Right Arrow = Pico arm moves Counter Clockwise (looking from the back of the Pico)
  • Left Arrow = Clockwise
  • 10000 steps at 500Hz = 1.25 turn
• Verified overnight data, but the air turbulence from the cleanroom is still too high (and motion at 15mHz too high) to have a good baseline. The hoqi noise is hovering between 10 and 100pm/sqrt(hz)>10Hz
• Created a folder under /ligo/svncommon/SeiSVN/seismic/HAM-ISI/H1/CRS to store and share CRS data, scripts and templates

CRS is ready for installation in chamber

Next:
Test that positive HOQI signal corresponds to the corner cube moving away from the sensor (same convention as OSEMs)
Calibrate the HOQI PDs to power
Install the fiber feedthrough and start cabling up in chamber
