Summary of the morning run

Note for beginner

• Time
  • JST or GPS time
• IFO config = Interferometer configuration
  • Yarm cavity : Lock the Yarm cavity by feedback to the IMC length (Almost frequency noise evaluated by Yarm length)
  • FPMI : Fabry-Perot Michelson interferometer. The h-of-t signal is calculated from DARM displacement
• Main channel
  • We should analyze this channel as h(t) channel
  • (1) K1:CAL-CS_PROC_XARM_FREQUENCY_DQ
    • Unit is Hz, because of calculating the IR laser frequency noise
    • Even though Yarm lock, the channel name is XARM. The same strategy to keep the cavity.
  • (2) K1:CAL-CS_PROC_DARM_DISPLACEMENT_DQ

    • DARM displacement [nm or m] there are still some bugs in the online model, I will summarize later Fixed(Due to the fail of the filter)

  • (3) K1:CAL-CS_PROC_MICH_DISPLACEMENT_DQ
    • Ogaki-san and cal team sometimes update the optical efficiency and actuator efficiency
  • (4) K1:CAL-CS_PROC_SRCL_DISPLACEMENT_DQ
    • First opt gain and act eff measurement 2019/08/30

  • Information related to the run is summarized here
• Memo
  • What is this?
  • In the future, we want to do the calibration line injection, PEM injection, add the excitation and check the noise, hardware injection, and so on.
  • We will write following information.
