Scientific paper

The Abu infrared imager consists of an ALADDIN 1024x1024 InSB array mounted in a cold-head cooled dewar capable of pumping down to operational temperature without cryogens, equipped with one-to-one transfer optics and an eight-position filter wheel. This simple system was operated at the South Pole on the CARA SPIREX telescope for two years, running in its second winter without trouble continuously for nine months. It was then modified slightly, mostly by inclusion of a higher quality ALADDIN II array, and used for commissioning of the Gemini South 8-meter telescope on Cerro Pachon in Chile. We discuss the lessons learned from the South Pole experiment, the changes made for operations on Gemini South, some results from both sites, and the future of this compact, reliable, and robust camera.
