The DSX400 X-ray source with linear drive.


Twin-Anode, High Flux X-ray Source with Long Lifetime


  • Twin-anode with two independent filaments
  • Standard anode materials: Mg and Al. Alternative anode materials available
  • High flux
  • Long lifetime
  • Minimal cross-talk
  • CE compatible
  • Optional linear drive and differential pumping

The DSX400 provides high flux X-ray radiation which enables intense photoelectron spectra. The dual anode makes it possible to change excitation energy without breaking vacuum and thus quickly verify measured data. The X-ray tube is designed with a narrow nose cone which ensures a short source-to-sample distance, also when combined with other techniques.

In the pursuit for great research results, DSX400 is a reliable addition to your analyser. It provides high flux magnesium and aluminum X-ray radiation without the need to vent the system when switching in between. The excellent life time makes sure that your hours are spent on research instead of service work.

A user-friendly GUI allows easy access to all parameters and the control electronics includes interlocks and auto-start-up procedures for safe and simple operation.

The standard DSX400 is equipped with an aluminum and a magnesium anode but other anode materials are available on request. High thermal conductivity of the anode and optimised water flow ensures efficient cooling. A thin aluminum window reduces Bremsstrahlung radiation and acts as a partial vacuum barrier enabling differential pumping of the X-ray source. The filaments are made of durable yttria-coated tungsten to ensure long lifetimes, even for high emission use.

The outer design provides high flexibility when mounted on a UHV system. For minimum working distance and multi-technique integration a 100 mm linear drive can be added.
