Abstract
A soft x-ray imaging device is disclosed having a housing defining a housing chamber. An optic post having a planar surface is secured to the housing so that the planar surface is positioned within the housing chamber. A phosphorus coating is applied to the planar surface of the post for converting electrons to visible light. A microchannel plate for converting x-rays to electrons is secured within the housing chamber so that the microchannel plate is spaced from and parallel to the planar surface of the optic post. An opening is formed in the housing in alignment with the microchannel plate and this opening is sealingly closed by a window which is made of a material substantially transparent to soft x-rays. This window also creates a vacuum tight housing chamber.
Claims15
A soft x-ray imaging device comprising:
- a housing defining a housing chamber,
- an optic post having a planar surface and substantially transparent to visible light and an annular mating surface surrounding said planar surface,
- means for securing said post to said housing so that said planar surface is positioned in said housing chamber,
- means on said planar surface of said post for convening electrons to visible light,
- means for transforming x-rays to electrons,
- means for mounting x-ray transforming means having a first and second side within said housing chamber so that said transforming means is spaced from and parallel to said planar surface of said optic post, said mounting means comprising a ring having two spaced annular surfaces, one annular surface on said ring substantially continuously flatly abutting and supporting an outer periphery of said first side of said x-ray transforming means,
- means for clamping said x-ray transforming means to said ring, said clamping means comprising an annular locking member substantially continuously flatly abutting an outer periphery of said second side of said x-ray transforming means.
A soft x-ray imaging device comprising:
- a housing defining a housing chamber, said housing having an opening,
- a window disposed across said window, said window being constructed of a material substantially transparent to soft x-rays and said window sealingly closing said housing chamber,
- means for continuously evacuating said housing chamber during operation of the imaging device,
- an optic post having a planar surface and substantially transparent to visible light and an annular mating surface surrounding said planar surface,
- means for securing said post to said housing so that said planar surface is positioned in said housing chamber and in alignment with said housing opening,
- means on said planar surface of said post for converting electrons to visible light,
- means for transforming x-rays to electrons,
- means for mounting x-ray transforming means within said housing chamber so that said transforming means is spaced from and parallel to said planar surface of said optic post,
- a ring in abutment with said annular mating surface,
- means for clamping said x-ray transforming means to said ring, said clamping means comprising an annular member substantially continuously flatly abutting an outer periphery of a side of said x-ray transforming means.
