Abstract

The next generation of X-ray astronomy instruments will require position sensitive detectors in the form of charge coupled devices (CCDs) for X-ray spectroscopy and imaging that will have the ability to probe the X-ray universe with a greater efficiency. This will require the development of CCDs with structures that will improve on the quantum efficiency of the current state of the art over a broader spectral range in addition to reducing spectral features, which may affect spectral resolution and signal to background levels. These devices will also have to be designed to withstand the harsh radiation environments associated with orbits that extend beyond the Earth’s magnetosphere. The next generation X-ray telescopes will incorporate larger X-ray optics that will allow deeper observations of the X-ray universe and sensors will have to compensate for this by an increased readout speed. This study will aim to describe some of the results obtained from test CCD structures that may fit many of the requirements described above.
