LIGO Document E1500121-v1
- ETM08 H1-x ~200ppm peak transmission at a radius of 38mm
ETM09 L1-y ~900 ppm peak transmission at a radius of 33mm
Probe beam spot size 1mm
Back of the envelope estimate is ~sub ppm loss for the arm cavity.
The diameter of the pinhole on ETM09 is estimated at 10-20 micrometers based on
the divergence of the beam coming out the back.
