This is work on April 16th.

A mirror for ML PLL moved again... We replaced the folk and fixed it. Then we re-aligned ML PLL fiber.

 

Current fiber coupling:

ML AUX1: 3.3 mW → 0.5 mW, coupling: 0.5*2/3.3 = 30%

ML AUX2: 4 mW → 0.5 mW, coupling: 0.5*2/4 = 25%

 

We checked space for telescope for a filter cavity and moved some folks and HWP in squeezing path to save space.

Then we re-aligned homodyne, but we couldn't see any squeezing at that time.
