Abstract
An improved sealed proportional counter window for an X-ray spectrometer includes a metallic foil having high X-ray transmission characteristics and having an ultra thin plastic coating thereon for sealing the inherent porosity of the metallic foil. The plastic coated foil is suitably supported by an arrangement which provides a relatively high percentage of unobstructed counter window area.
Claims6
A window for a proportional counter used in an X-ray spectrometer, comprising:
- a thin metallic foil having a high X-ray transmission capability for passing a relatively wide range of X-ray spectra;
- the thin metallic foil having a thin plastic coating thereon which is essentially X-ray transparent;
- the proportional counter including a housing having an open area;
- and
- means supporting the thin plastic coated metallic foil and supported in the open area of the housing for providing a proportional counter window having a relatively large unobstructed window area.
