Suspension commissioning details and plans? [Terrence]
- Has it been discussed? To me, it is still very unclear how it should be done and what people expect. If it has been discussed before, it seems to me it is not transparent.
- I would like to call for a meeting. In the meeting, we should discuss how should SC be done, including but not limited to topics like:
- The scope of the suspension commissioning.
- What are some deliverables?
- How should tasks be done? (E.g. Sensor alignment, noise estimation, etc..)
- What methods should we use? (I propose to use a benchmark so we accept multiple methods, for now.)
- What are some evaluations that should be done? (E.g. We should make a report for each suspension about what has been done and what are some objective quantities that we measured to confirm the performance of the suspensions)
- How to interface with interferometer commissioning? (We shouldn't think of suspension commissioning as something that can be done once and for all. Instead, we need to get input from the interferometer and recursively update our strategies.)
- Someone should roughly plan out the timeline (at least from start to finish).
- I will be drafting a document, which I hope to serve as a handbook/rules for suspension commissioning so everything is clear to everyone.
I found Miyo-san's suspension comissioning document JGW-E2112444-v2. But there are many more things that I would like to address and discuss in detail, for example, how exactly should we do sensor diagonalization? How should we measure performance?
- Which mailing list should I use, to organize the meetings? gokagra?
