Laser Power after fixing the laser chiller: more traces |

If you look at the correlation between RMTEMP and HTEMP, you see what we knew: namely that there
was a 1:1 correlation before. After the chiller fix, I can see no correlation between the room and
amplifier temperature at the resolution of 10:1. So the chiller loop has a gain > 10 at 24 hour time
scales.
I don't understand why the PMC looks more stable. |
