The development of the 2nd generation ARTAX was based on experience acquired from a large number of installations of the original version. Improvements include safety features, data sampling capabilities and user comfort.

Fast exchange of excitation sources

The measuring head consists of a central unit containing the detector, the CCD camera and the laser spot. The excitation unit, consisting of tube housing, X-ray tube and X-ray optics, is mounted on the side, fixed by a high precision lock, which allows a fast exchange. Including cable connections and warm-up of the tube the exchange can be done in less than 15 minutes. This enables the user to choose the most suitable excitation sources or target materials and also allows fast exchange of the X-ray optics.

Mo tube - Significantly better excitation of light elements

The differences in the detection limits through using the tube target materials Molybdenum and Tungsten could be demonstrated for representative elements from a variety of samples (bronces, glasses, metal alloys). It can be shown that the X-ray tube with W target generates 2 to 5 times larger peak areas for K-line elements above 20 keV. In contrast to that the Mo tube shows its major advantage in the significantly better excitation of light elements.

Features

  • Improved accessibility of samples due to a more compact measuring head design and an increased distance to the sample.
  • Touch sensor for avoidance of damage to the art object
  • Improved radiation safety by an additional control terminal for direct access to basic functions
  • Three safety contacts for additional warning lamps, door interlocks etc.
  • Software control of the He flow for light element detection and the laser spot for positioning
