TITLE: 09/10 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

DRMI locking work continued, but the afternoon focused on ETMx investigation/troubleshooting (look for an alog on this later).

The Relay Tube was opened up to the main volume (HAM7 & "downstream" remain isolated and pumping down).
LOG:

• All Day:  BT Enclosure patch work; just passed the +3km mark (randy)
• 1500-1540 Morning Alignment:  Started aligning of cavities noted in Elenna's alog notes);  Took ISC_LOCK to MANUAL_INTIAL_ALIGNMENT: 
  • Green Arms:  Used INIT_ALIGN & selected GREEN_ARMS_OFFLOADED
    • Y-arm had decent flashes, but X-arm was not as good--tried tweaking a little by hand but SCAN ALIGNMENT took over & finished the alignment.
• NOTE:  After Green Arms, used ALIGN_IFO to select different states for aligning other cavities
  • Xarm IR: (completed WFS CENTERING XARM)
    • When Elenna arrived, we checked this again at XARM_IR_LOCKED (I think this was at 1, so no changes made)
  • PRX: (completed WFS CENTERING PRX),
    • Elenna had me redo PRX alignment:  Since no WFS, because rfpds need to get rephased after DRMI work
    • Hand Tweaks:  Went to PRX_LOCKED & then tweaked PRM to maximize AS_A_DC
  • Mich Dark: (lockloss at MICH DARK ALIGN, so I skipped this after 2nd attempt). 
    • Hand Tweaks:  Then just tweaked BS by hand by taking to MICH DARK LOCKED and tweaking BS to optimize Dark spot for AS AIR (or minimize AS_A_DC)
  • SR Align: (This is when Elenna arrived and helped me)   edit:  (completed to PREP SRC ALIGN)
  • SRY:  Go to SRY_LOCKED
    • Hand Tweaks:  While locking, SRM tweaked-up fringes (highs high/low low) 
    • SRY locks and then continue SRM tweaks to maximize AS_A_DC
  • SR2 (completed OFFLOAD SR2 ALIGNMENT)
  • PRX Again:  Make sure PRM is tweaked up (with Elenna)
    • PRM used to maximize AS_A_DC
• 1500-1548 optics lab (kim)
• 1613-1825 spackle 2hrs (chris)
• 1600-1710 TCS Property sorting (tj,christina)
• 1749-1758 H2 room clean (kim)
• 1815-1845 checking on key for a door (tj,richard)
• 1846-1909 Connect Relay Tube to Main Volume (HAM7 will remain valved off to continue pumping down) [gerardo.jordan]
• 2101 Moving parts from Corner to H2 Bldg & MY (fil + marc joining)
• 2125 Plugging in cable at psl racks for JAC measurement; but it was already connected (sheila)
