Abstract

This paper is intended primarily for the LAMOST UCAM CCD systems. The illustrations given here show the prototype LAMOST UCAM systems. Designed as a universal CCD controller, the UCAM system has variety options of readout modes, sampling speeds, binning options and charge clean. Its main components, architecture and technical design are introduced here. Some important performance characteristics about the UCAM controller and the e2v-203-82 CCD (4K by 4K, blue CCD) are tested under laboratory conditions, such as readout noise and gain at different sampling modes and readout speeds, CTE, dark current, QE, and fringing. Perfect CTE and less than 3 electrons / pixel system readout noise prove that the UCAM CCD controller system meets the requirement of the LAMOST telescope.
