Scot Kleinman, Benoit Neichel, and Maxime Boccas Instrument Development Update The development team at Gemini and its partner institutions are nearing completion on a variety of ongoing instrument projects. This report presents updates on most of the projects currently underway or in planning. Since our last report in the June 2012 issue of GeminiFocus, the development team at Gemini, and our large family of partner institutions throughout the Gemini community, have worked hard on a variety of ongoing instrument projects. Many of these are nearing completion, and a few are just getting started. Here we provide a brief status report on our largest projects. GeMS Progress Figure 1. A portion of the star cluster NGC 1851 acquired in H-band. The full-width at half-maximum of the stars are around 120 milliarcseconds and uniform across the 85 x 85 arcsecond field-ofview of GSAOI. Since May 2012, the Gemini Multi-Conjugate Adaptive Optics System (GeMS) has been in engineering shutdown. As in 2011, we decided to exploit the Chilean winter (during which time conditions are less favorable for AO observations) to work on several upgrades for GeMS. We had three main objectives: 1) to optimize and improve the sensitivity of the Natural Guide Star Wave-Front Sensor (NGSWFS); 2) to add remote control and automation in the Laser and Beam Transfer Optics; and 3) prepare the instrument’s software for the transition of GeMS into operations.
