External Beam

The Surrey Ion Beam Centre has a focussed external beam line for analysis of objects under ambient pressure conditions. 

The External Beam Line at Surrey was commissioned in February 2004. The beam exits through a thin Si3N4 window. It can be focussed to about 10 microns in size and can be raster scanned across a sample.

The external beam line is useful for analysis of objects which are not compatible with vacuum i.e. they are:

  • too big
  • too fragile
  • too valuable to take samples
  • alive (e.g. plants or cells) 

It has been used for non-destructive analysis of museum samples to:

  • Investigate ancient technologies
  • Provenance Raw Materials
  • Study ancient environments and lifestyles
  • Aid conservation studies
