ABSTRACT:
An X-ray detector including a photocathode arranged to receive X-ray radiation and being operative to provide in response thereto an output of electrons, and at least one electron multiplier operative at subatmospheric pressure and in response to the output of electrons from the photocathode to provide an avalanche including an increased number of electrons.
