noise budget injections

Sheila, Kara

We got a set of noise budget injections in while LLO was doing some commisioning, with the new PRCL FF, SRCL offset, and the curent spot positions. 

We used a reference time of  Sep 05 2019 22:31:51 UTC, we turned off the squeezer for a no squeezing reference at Sep 05 2019 23:06:57-23:17:00  UTC

We did a light set of injections, including PRCL, SRCL, MICH, intensity noise, frequency noise, IMC PZT P+Y, and CAHRD and DHARD. Results will be posted tomorow.

Here are the results of yesterdays noise budget injections when the squeezer was on.

We are being limited by laser intensity noise at higher frequencies, which have gotten worse since our last noise budget (see Georia's alog 50104).  In Georgia's alog, the shot noise was not correctly budgeted for.  This is true in our noise budget as well, but it is not as obvious due to the increased intensity noise.
