| Abstract: | The excellent X-ray images produced by X-ray telescopes require the use of detectors with imaging capability at the focal
plane of the telescopes. In this concluding part of the article on experimental techniques in X-ray astronomy, I describe
many X-ray detectors that have been used over the years. These can broadly be classified into two physical types: non-dispersive
and dispersive. Traditionally the simple non-dispersive types have been used extensively in X-ray astronomy. The advancement
of solid state technologies, cryogenics, and the quality of X-ray imaging has led to many new detectors of both types. Both
the traditional and the new types of detectors are described briefly here with emphasis on principles and some technical details.
Kulinder Pal Singh is in the Department of Astronomy and Astrophysics of the Tata Institute of Fundamental Research, Mumbai.
His primary fields of research are X-ray studies of hot plasmas in stars, supernova remnants, galaxies, intergalactic medium
in clusters of galaxies, active galactic nuclei, cataclysmic variables and X-ray binaries. He is leading the development of
a soft X-ray imaging telescope for the ASTROSAT mission to be launched by India in 2007–2008.
