FINAL A&T STAGES OF THE GEMINI PLANET FINDER

The Gemini Planet Imager (GPI) is currently in its final Acceptance & Testing stages. GPI is an XAO system based on a tweeter & woofer architecture (43 & 9 actuators respectively across the pupil), with the tweeter being a Boston Michromachines 64 2 MEMS device. The XAO AO system is
