NGWFC Parametric Oscillator for tip/tilt vibration reduction

Project on hold as of Sept 9, 2010

• Parametric_Oscillator_delayed_for_now.pdf: Chris' email regarding delay

Team

• Lead: Kevin Tsubota
• Scientist: Chris Neyman
• Software: Sudha LaVen
• Ops Tools: Olivier Martin

Goal

This is a proof of concept identified as a NGAO Detailed Design Risk Reduction task. The goal is to evaluate the effectiveness of a parametric oscillator in reducing a 29hz observatory wide vibration using the existing Keck-2 NGWFC tip/tilt system.
