Type-A
[Miyo] Installed the Prequa system in TypeA
- (This week) Installation was finished. Now I try to diagonalize sensors and balance actuators by using the Prequa system.
- (Next week) I will do the modal damping on TypeA suspensions after the initialization work for sensors and actuators.
Type-B
On Monday I submitted the paper to CPC: JGW-P2011860.
Noise budget paper: I calculated upper limits to DAC and coil driver noise contribution to DARM for the BS: klog 14875.
Type-Bp
Noise budget paper: Fabian calculated upper limits to DAC and coil driver noise contribution to DARM for PRM: klog 14876.
Type-C
Controls
Electronics
Towards O4
KAGRA is in "Upgrade phase for O4". PreQua system was implemented to the Type-A.
- Confirmation of personnel at the site.
- Type-A team: Takahashi, Sato, Miyo, + Company(Jan-Apr)
- Type-B/Bp team: (Shoda,) Hirata, Fabian, Washimi, + Company(Oct-Dec)
- Procedure documents are required by SEO.
- Wire gluing in PR3 (by Shoda)
- Filter height adjustment in Type-B (by Fabian)
Schedule towards O4 (Chart) was revised.
cf. Post Obs. task (Request), Task for O3c (Plan, Sheet), Task towards O4 (List).
