More EPIC ImagesOne of the three EPIC Cameras. The conical radiator cools the CCDs to their operating temperature of -100 degrees C.
One of the EPIC Camera MOS CCDs. Two of the cameras use this type of metal oxide semiconductor CCD. These detectors register photons in the lower energy portion of the X-ray spectrum with good energy resolution.
The mechanical assembly of the MOS CCD array. The central CCD is located in the central part of the mirrors' focus, and the surrounding 6 CCDs are set above the central device to better approximate the curved focal plane surface.
The power and read-out electronics for the 12 CCDs of the p-n camera.
The development of the p-n detector was a seven-year effort by the semi-conductor laboratory of the Max Planck Institute for Extraterrestrial Physics, followed by over two years of integration work and testing on the camera itself. The result is an EPIC p-n detector with a single chip, whose design represents a radical departure from the integrated circuit conception of current MOS CCDs. The p-n detector performs efficient detection of the high energy X-rays.
