Patent ID: 7022994

Claim:
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.
