Design of the KMTNet large format CCD camera

摘要

We present the design for the 340 Mpixel KMTNet CCD camera comprising four newly developed e2v CCD290-99imaging sensors mounted to a common focal plane assembly. The high performance CCDs have 9k x 9k format, 10micron pixels, and multiple outputs for rapid readout time. The camera Dewar is cooled using closed cycle coolers andvacuum is maintained with a cryosorption pump. The CCD controller electronics, the electronics cooling system, and thecamera control software are also described.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
