Progress report
General
Miyo-kun is gathered information about LVDTs at JGW-T2011597. Feedback seems to be required.
Type-A
Revising the Type-A installation procedure.
Type B
For a summary of the current status of inertial damping in Type-B suspensions see the appendix (p14 onwards) in the presentation shown the Commissioning Meeting on the 27th of September 2019.
In the context of writing a paper I gathered information about OSEMs and LVDTs and uploaded a document at : JGW-T2011612, which I will be updating.Currently the content is
- Linear ranges of 24 OSEMs and
- Sensitivity of the six SRM OSEMS.
- I gave feedback to Miyo-kun about LVDTs.
Type-Bp
Type-C
Electronics
Post O3 (4/21~)
- Papers (Type-B: Fabian, Type-A:?)
- Operation mode at the shutdown of KAGRA
Towards O3c
Controls
Had a VIS control strategy meeting documents
