  • 8:40am, in chamber, balanced
    • S1600453 in CR1
    • S1600491 in CR2 (i meant to install 490, but got confused)
  • 10:23am, roughing pump on, clamps on
  • 10:32am, turbo pump on
  • 3:01pm, something is wrong with CR1 (the 666 Hz line due to the turbo pump is very large and saturates the QPD signals). Venting
  • 4:11pm in chamber
    • S1600453 in CR1
    • S1600490 in CR2
  • 4:12pm roughing pump on, clamps on
  • 4:20pm turbo pump on
