Peter Takacs with a test system that measures the imaging performance of charge-coupled device sensors used in the Large Synoptic Survey Telescope camera that is under construction in Brookhaven's Instrumentation Division. The integrating sphere on the left provides uniform illumination onto the sensors mounted in the vacuum chamber to the rear. A custom-made electronics board, held by Takacs, is used to record the images produced by the sensors. About 200 of these sensors will be used in the complete camera when the telescope begins operations in Chile in 2020.
