The following tasks will be finished within the next 24h:
- aligning both cavities
- align beat
- install RF-AM PD (start with one to get estimate for noise budget)
- measure TF from seismic to beat (if possible, vacuum chamber temp might not be stable enough)
we will then focus on (re-)measuring some things we need very soon for a more accurate NB (there are more but the following ones are my favorites for now. We are about a factor of 3 above the CTN @200Hz)
- RF-AM - not in NB yet, but seems to dominate 100Hz-1kHz region, so we do this first (seen last week while optimizing everything)
- RIN - old measurement must be wrong as it is too high
- seismic - new stack, so new TF
- phase noise of Marconi locked to rubidium clock - we know that the noise will be less below 1kHz, above it most likely does not change the phase noise level
- electronic noise from both PDH loops
