Vibration isolation and control of sensitive systems – 2 hours

Activity Leader: Fabrice Matichard, Visiting Research Scientist

The presentation will give a general introduction to the problem of vibration isolation.  We’ll discuss the following concepts:

– Passive isolation principles
– Static deflection
– Damping
– Transmissibility and compliance
– Multi-staging
– Active isolation principles
– Block diagrams
– Loop shaping
– Absolute versus relative control
– Inertial sensors
– Sensor Noise
– Sensor Fusion
– Noise Budgeting
– Feedforward control

We’ll finish the presentation by a review of vibration isolation systems used either in the industry or in physics experiments.

Presentation 9:00-11:00 in Marlar Lounge 37-252.  A tour of the LIGO labs will follow the presentation.  Pre-requisite for taking the LIGO labs tour is attending the presentation.

Requirements: basic knowledge of Laplace/Frequency domain formalism.

Presentation and tour limited to 16 people.  Advanced sign up required by 4pm on January 6.
