Abstract

A system is described whereby X-ray fluorescence analysis of elements below atomic number 19 (potassium) is undertaken with a “windowless” demountable X-ray tube. Comparison is made with 100-μ- and 30-μ-thick beryllium windows- Deflection plates are required before or behind the sample to eliminate scattered electrons. A high-resolution X-ray diffractometer is also described by making use of a fine focal line on the target. Burn-through due to localized heating on the target is eliminated by using a thermocouple arrangement.
