STATE of H1: Planned Engineering
INCOMING OPERATOR: n/a tonight
SHIFT SUMMARY:

LOG:

• 2310 Locking
  • 0011 OMC Whitening & Cal Lines were turned off, so.....
  • 0011 DARM OLG measurement run (elenna)
  • 0024 LOCKLOSS
• 2340 Had trouble bring up the alog webpage (could bring up other CDS webpages (on my gc laptop and and 
• 0009 Francisco out of PCal Lab
• 0024 Locking
  • Ran check Mich Fringes + PRMI since DRMI was not great.  Once PRMI locked, touched up with PRM since it is currently not used for ASC.  DRMI then locked fine.
  • Also, for this lock, Elenna guardianized ISC_LOCK to get H1 
  • 0134 OMC Whitening
  • 0136 LOCKLOSS
• Game Plan For night: 
  • Want to run the Simulines calibration measurement as soon as H1 completes the NLN state---Last week, H1 would lose lock from simullines, so this is to see if there's still issue. 
  • If H1 makes it through simullines, check on SQZ.  If SQZ has issues, contact Vicky for touch-up
  • Once H1 is thermalized, run full suite of calibration measurements
• 0137 Next Lock
  • spent time tweaking PRMI (instead of running a more full alignment); this eventually worked
  • 0301 Max Power complete (So this is the "start time for thermalization"  I thought I heard people say after 2hrs is fine for thermalization, but the wiki says 3hrs.
  • 0309 OMC Whitening & waiting for violins to damp---so Calibration could be run
  • 0320 Flipped sign on ITMx Mode13 gain to -0.2
  • 0321 NLN (but not fully green due to OMC Whitening/rung up violins)
  • 0511 LOCKLOSS!!!  :(
• 0357-0421 SimuLines measurement started.  This is not an "official" measurement because H1 is not thermalized.  This is mainly to see if this measurement causes a locklosses as noted on Jun5 (alog 84834).  This successfully completred measurement did NOT cause a lockloss.
• 0435 switch ITMy M5 from FM6+FM8+FM10, gain= 0.01  to (2W settings of) FM6+FM7+FM10, gain = 0.01 (because this mode was the only one increasing after about an hour into the lock.  
  • Ultimately saved these settings in the hopes of running over night (but we had a lockloss).  
  • 0526 Saved lscparams & LOADED ISC_LOCK and VIOLIN_DAMPING_STATES nodes.
• Taking ISC_LOCK to IDLE overnight because H1 has been requiring assistance for alignment of DRMI most of the day.
