Scientific paper

The pn-CCD (Charge Coupled Device) is a novel type of CCD developed for fast X-ray imaging and spectroscopy for the X-ray Multi Mirror (XMM) satellite mission. Each 200 by 64 pixel large pn-CCD unit with a sensitive area of 3 by 1 sq cm is a fully depleted detector. With the use of the CMOS Amplifier and Multiplexing chip (CAMEX64B) it is possible to read out the 64 CCD channels in parallel before they are multiplexed and sent to an ADC. For the first time the system of a 64 channel pn-CCD together with CAMEX64B readout, ADC conversion, and data acquisition and storage has been brought into operation. First images of an Fe-55 X-ray source are presented and discussed.
