| Résumé | After more than six years of successful operation at Gemini South, the Gemini Planet Imager (GPI) will be moved to Gemini-North. During this move, the instrument will undergo a series of upgrades. One of these upgrades will be the installation of a new pyramid wavefront sensor (PWFS) with a low noise EMCCD detector that will replace the current Shack-Hartmann WFS. This upgrade is expected to significantly increase the sky coverage of GPI, providing increased level of AO correction and access to fainter targets. The new PWFS will be assembled on a standalone bench that will be aligned and tested independent of the GPI to ensure the required performance is achieved. Once the performance is verified, the completed subassembly will be installed in place of the current WFS hardware during the final integration into the GPI. In this paper, we will present the final design of the new GPI PWFS. Included will be a description of the optical performance simulations completed and their results, and a detailed overview of the opto-mechanical design of the new PWFS bench. |
