Laser Guide Star Facility (LGSF) Upgrade: Next Generation Laser Guide Star for Gemini South Given reliability issues experienced with the existing laser guide star system at Gemini South, Gemini is investigating procuring a new laser. The current generation of laser systems are much more reliable than our existing laser, which is difficult to maintain at full power, making its use operationally both costly and technically challenging. GMOS: CCD Update at Gemini North With new red-sensitive Hamamatsu detectors installed and commissioned in the Gemini Multi-Object Spectrograph (GMOS) at Gemini South, and with the CCDs providing good science data, it’s now Gemini North’s turn to have its GMOS upgraded. The new Hamamatsu detectors should arrive at Gemini North in early 2015. After assembling and testing the new CCDs in the lab, we’ll be ready to install them in July 2015, pending operational resources being available. Details and updates are available here. In early 2015, we will explore the feasibility of integrating a current generation laser with the rest of our laser guide star system. If this integration is feasible and the new solution meets our power, reliability, delivery time, and cost requirements, we will strongly consider moving forward with procurement.
