Cavity Control Influence on Damping

Document #:

LIGO-G1200774-v1

Document type:

G - Presentations (eg Graphics)

Abstract:

Follows the example of DARM hierarchical control to illustrate how suspension modes move with hierarchical control applied to one pendulum and two pendulums. Any advanced high performing damping loops that depend on precise mode frequencies will need to take this effect into account.
