Huang, Y; Hoerning, J M

This patent describes a radiation detection apparatus coolable to cryogenic temperatures comprising: (a) an outer vessel having walls defining an interior cavity therein; (b) an inner vessel disposed within the interior cavity of the outer vessel and itself having walls defining an interior cavity for holding cryogenic coolant; (c) means for supporting the inner vessel within the interior cavity of the outer vessel with the walls of the inner vessel spaced away from the surfaces of the outer vessel and for providing communication between the ambient atmosphere and the interior cavity of the inner vessel; (d) window means for providing transmission of radiation to be detected through a window to an opening in the outer wall of the outer vessel while sealing off the vacuum chamber defined between the inner and outer vessels from the ambient atmosphere; (e) a mounting member formed of a highly heat conductive metal mounted to the bottom surface of the inner cavity in heat transfer contact and extending outwardly and thence upwardly from the point of mounting in the vacuum chamber in spaced relation to the walls of the inner and outer vessels to a position at the opening in the outer vessel at which the window structure means is mounted; (f) radiation detector means for detecting incident radiation and providing an output signal indicative thereof.
