摘要

The Physics of Accelerating Universe Camera (PAUCam) is a new camera for dark energy studies that will be installed in the William Herschel telescope. The main characteristic of the camera is the capacity for high precision photometric redshift measurement. The camera is composed of eighteen Hamamatsu Photonics CCDs providing a wide field of view covering a diameter of one degree. Unlike the common five optical filters of other similar surveys, PAUCam has forty optical narrow band filters which will provide higher resolution in photometric redshifts. In this paper a general description of the electronics of the camera and its status is presented.
