Paper Abstract

The Gemini Observatory is currently in the early stages of a major upgrade of the Secondary Mirror Tip/tilt Systems (M2TS). Although these systems continue to deliver good fast-steering and chopping performance at both sites, there are persistent and occasionally time-consuming issues that need to be addressed in order for them to deliver their full potential and further reduce downtime. We present an overview of the system, outline its capabilities, and review the early commissioning process and some of the issues encountered. We describe the augmentation of the original system with data logging features which made possible some critical servo tuning work that was key in delivering improved performance. The hardware and software upgrade project to date is discussed, along with a brief overview of items it intends to address.
