4. transversal coil check implementation of qz (left pending)
5/10/2019 HW
All the available handles to make possible flexible and specially featured strategies to cope with environmental and commissioning issues have been implemented.
Just few open issues:
x damping ….
scheduled shifts: 1
Target:
transversal coil check
implementation of qz (left pending)

“(dinamically) soft download” almost ready
Issues to complete it:
Automated suspension re-centring
Operator interface up-date SW
scheduled shifts: 1 + off-line work (…)
Target:
to allow tests of environmentally featured filters during any commissioning shift

5/10/2019
CIPC tested using the scheme
4G+2NoG: incoherent behavior of
zCorr, F0, when suspensions with NoG are excited
Shifts spent: 3 (not so many…)
Siesta modeling proposed
in parallel to std control design
CIPC Modeling/test phase started,
but no clear understanting so far.
Quite reasonably this matter is combined with the spectral blending of Pos versus Acc
Strategies
LP/HP Modeling/test phase started, but no solution addressed yet.
Few hours of shift taken (n.s.m.)
It was foreseen from the beginning
both GIPC and std ID will improve

10. Vdamp vertical damping (y) implemented in 6 towers

vertical damping (y) implemented in 6 towers
basically the same filter used for horizontal ID 70 mHz).
only top sensor used (F0)
mseism rms reduction
(NS-NS Horizon > 0
last night).
gain optimization
under study
short towers ?
(next step,
probably, urgent)
