Power calculation
P_arm = Plaser * T_PMC * T_IMC * T_FI * alpha_MM * G_PR * T_BS * G_arm
(Gautam put some numbers here for the terms please)
- What should our PMC Finesse be so that its barely enough to satisfy filtering reqs and transmission efficiency?
- Suppress angular modes by XX (note that the IMC also filters the beam jitter)
Suppress laser noise at the 11 & 55 MHz readout frequencies by XX (this is primarily a PMC function as the IMC transmits the sidebands)
Maintain a T_PMC > 0.9X
- What's up with our T_IMC ?
- let's clean the IMC mirrors
- what's the MM frac between PMC and IMC?
- Is our T_FI too low?
- measure this during the vent when we clean the IMC
- What is the loss in the PRC?
- clipping in the PRC
- new PR/SR mirrors
