Fluorescent X-ray analyzer with sealed X-ray shield wall |
摘要 |
A X-ray analyzer can generate an X-ray beam for application to a sample position during a support sample stage. An X-ray shield wall having an aperture transmissive to the X-ray beams is positioned adjacent to the supporting sample stage with a transparent film member sealingly extending across the aperture. An X-ray detector is positioned adjacent the X-ray shield wall. The upper side of the X-ray shield wall can be sealed and placed in a vacuum state or backfilled with a gas such as helium. The sample can be mounted at atmospheric pressure beneath the aperture and X-ray shield wall whereby improved transmission and detection of X-rays is achieved.
