Abstract

The Gemini Planet Imager (GPI) is undergoing a number of upgrades as part of the process of moving the instrument from Gemini South to Gemini North. The upgraded instrument (GPI2.0) will include a new Real- Time Controller (RTC) that drives the eXtreme Adaptive Optics (XAO) system, which is composed of a new high-sensitivity Natural Guide Star (NGS) Pyramid Wavefront Sensor (PWFS), and the existing two Deformable Mirrors (DMs) and Tip/Tilt Stage (TTS) at loop rates up to 2 kHz with very low latency. The new RTC is based on the Herzberg Extensible Adaptive Real-time Toolkit (HEART), which is a collection of libraries and other software that can be used to control different types of Adaptive Optics (AO) systems. HEART’s configurability and flexibility lends itself well to GPI2.0 RTC. This paper explores how HEART functionality is used and configured to construct the GPI2.0 RTC.
