Abstract
A radiation converter has a radiation absorber for generating photons dependent on the intensity of incident x-ray radiation, a photocathode arranged downstream of the radiation absorber in the radiation propagation direction at a distance therefrom and serving for generating electrons dependent on the photons emerging from the radiation absorber, a device for accelerating the electrons emerging from the photocathode onto an electron detector for generating electrical signals dependent on the impinging electrons, an electron multiplier arranged between the photocathode and the electron detector, the electrons emerging from the photocathode being multiplied by the electron multiplier.
Claims13
A radiation converter comprising:
- a radiation absorber for generating photons dependent on an intensity of x-rays incident on said radiation absorber;
- a photocathode disposed downstream of said radiation absorber in a propagation direction of said x-rays at a distance from said radiation absorber, said photocathode generating electrons dependent on said photons emerging from said radiation absorber;
- an electron accelerator disposed for interacting with said electrons emerging from said photocathode for accelerating said electrons emerging from said photocathode;
- an electron detector on which the electrons accelerated by said electron accelerator are incident, said electron detector generating electrical signals dependent thereon;
- an electron multiplier disposed between said photocathode and said electron detector, for multiplying said electrons emerging from said photocathode;
- and
- a gas tight housing containing a UV photon-absorbing gas in which said radiation absorber, said electron multiplier and said electron detector are disposed.
