CdZnTe Focal Plane Detector
In recent years various instruments on board satellite missions have
demonstrated the need to extend high sensitivity measurements with
fine angular resolution coupled to good spectroscopic performance
into the hard X-ray regime.
These requirements have stimulated the development of hard X-ray
focusing optics such as multilayer concentrators.
The effort in hard X-ray optics development has led to the design of new
focal plane detectors capable of meeting the requirements posed by this
kind of optics, in particular in terms of high-energy detection efficiency,
spectroscopic capabilities and position resolution.
Among other high-Z semiconductor materials, Cadmium Zinc Telluride (CZT)
pixel detectors show very good spectral (< 5% @ 60 keV)
and spatial resolution (down to tens of Ám) and are suitable for use
in compact hard X-ray sensors operated at room temperature in
the (10 - 100) keV energy band.
IASF-Palermo is involved in the development of a CdTe-CZT
focal plane prototype to be used in a balloon borne mission and,
in particular, has the responsibility of the pixellated detector.
