Sensors of World’s Largest Digital Camera Snap First 3,200-megapixel Images at Slac

Crews at the Department of Energy’s SLAC National Accelerator Laboratory have taken the first 3,200-megapixel digital photos – the largest ever taken in a single shot – with an extraordinary array of imaging sensors that will become the heart and soul of the future camera of Vera C. Rubin Observatory.
