< Back Largest Digital Camera Linear Systems Mar 17, 2023 Engineering the World’s Largest Digital Camera Largest Digital Camera Big Science Project using Linear Systems' JFETs Advances SLAC's Large Scale Synoptic Telescope uses 2,000 Linear Systems LSK489 JFETs! The Large Scale Synoptic Telescope (LSST), which uses 2,000 Linear Systems LSK489 JFETs in its front-end amplification stage, is assembling what will be the world's largest camera when completed. This article describes the part of the project that includes our semiconductors: https://www.symmetrymagazine.org/article/engineering-the-worlds-largest-digital-camera Engineering the world’s largest digital camera | symmetry magazine www.symmetrymagazine.org A game of ‘Operation’ “When you consider a project this complex, you can’t just dive in and say ‘Here, I’m going to design and build this in one shot,’ right?” says Tim Bond, head of the LSST Camera Integration and Test team at SLAC.
