[Terrence] Just a reminder of the existence of this suspension commissioning document
- This is a compilation of various knowledge and techniques related to suspensions (mostly software).
- I hope this document can help the upcoming suspension commissioning and, more importantly, for longevity as people left KAGRA along with their methods.
- I have compiled a comprehensive list of suspension commissioning tasks to be done. (These tasks are foreseen to be recurring in the future.)
- The list consists of ordered tasks focusing on satisfying residual motion and displacement noise requirements.
- I am still writing the method sections, which consist of methods on how to complete the tasks.
I have also been programming these techniques as I write them, so implementation will be readily available. Kontrol tutorials are available here.
- I will be working on this. I hope to finish this in one-two weeks. I will be updating the progress.
- Please have a sneak peek and tell me if you any comments or questions, or if you think that there are some other important things to be added in the document.
