To-Do or things done, nearing closeout

Betsy, Camilla

PSL locked out at 2W. ALS shutter closed. LVEA now in laser safe.

Now nearing closeout of HAM1 ISC/IO (Final cable routing tweeks, SEI table float/bal, and final SUS TTs up next for a day or so):

  Stat Notes
All LSC/ASC diode boxes functional and aligned DONE All have appropriate channel response
Finish BDs in front of POP diodes DONE Could see with MICH/POP flashes
Beam Diverters functional and reflection beams dumped DONE Daniel swapped the REFL logic which we needed to do for the new beam layout.
4 Pico-motors tested, center-ish in range DONE All functional. Still need to recenter POP LSC.
4 Beams aligned out of chamber, through VP simulator and onto ISCT1 DONE Will need to work on ISCT1 to finish alignment once chamber closed
Finish aligning all beam dumps DONE In progress, status in 84321.
Final RF check - Sigg    
Final ground loop checks (diodes, PM1, picos, BDVs)    
Post SEI table float, last beam check prior to door   Might need a tweek if PM1 gets any SUS adjustments
Removed metal name tags DONE  
Removed temp mirror knobs DONE  

Updated Tuesday 13th May to mark the following as DONE: finish BDs in front of POP diodes, 4 Pico-motors tested, center-ish in range, Finish aligning all beam dumps, Removed temp mirror knobs. All laser hazard tasks completed (we may do a final check before closeout).
