A list of useful numbers for noise budget calculation.

 

==Reference Cavity==

  • Cavity Finesse:  10^4    PSL:424
  • Free Spectral Range:  737 MHz <=> cavity length = 8" = 0.2 m
  • Cavity Pole = 38.7 kHz.
  • FWHM = 2xcavity Pole = FSR/Finesse = 73.7 kHz
  • Spotsize on mirror = 291 um

 

==PMC==  PSL:370

  •  Finesse: 188
  • FSR     : 714MHz
  • FWHM: 3.8MHz
  • P-polariztion

 

==35.5MHz RFPD==

  • RFPD noise level:

==NPRO==

  • Fast actuator calibration factor: 3.07 MHz/V psl:182
  • Slow actuator

==LIGO VCO==

  • Tuning range vs frequency psl:22

==Beat==

  • Marconi(IFR2023b) calibration factor = 70e3  Hz/V for 160MHz carrier/ 100kHz input range (tuning range)
  •  Marconi(IFR2023b) calibration factor = 7e3 Hz/V   for 160MHz carrier/  10kHz input range

==Seismic Stacks==pslL668

  • translation beamline: f0 = 6.96 Hz  Q = 21.53
  • Vertical motion          f0 =  Q= 
  • Horizontal transverse, f0 = 6.35Hz, Q = 25.85
