I14 Technical Workshop: Engineering for nano beamlines

The aim of the workshop was to get together engineers and scientists who have dealt with the technical issues related to nano-science facilities to hear about the latest developments and challenges in this area

Event details

As part of the Diamond Phase III project, a hard x-ray nanoprobe will be installed on beamline I14 and will come into operation in mid-late 2016.

 
The final proposal for the nanoprobe came from the fusion of a micro/nano SAXS proposal aiming for beam sizes between 100nm and 1μm and a hard x-ray nanoprobe proposal aiming for sub-30nm focussing.
 
I14 will provide a state of the art facility in which a focused x-ray spot is positioned or scanned over a specimen. The central theme of the beamline is the ability to obtain structural and chemically-specific information on a full range of materials (inorganic/organic) under both static and real (e.g. wet, heated, in-situ strain) conditions, providing a facility that will be new to the UK.
 
The HXNP aims to provide:
  • Spatial resolution down to 25nm (10 nm may be possible with future optics developments)
  • Long working distances
  • Wide energy range (6-25 KeV)
  • Raster scanning capability for fast acquisition and increased sample area coverage.
  • XANES mapping capability
  • Simple data acquisition software with a strong emphasis on fast post acquisition data processing
Developing a nanoprobe facility that meets these requirements is challenging and issues related to the vibrational, mechanical and thermal stability need to be considered in detail both for individual components and the beamline as a whole.  The aim of the workshop was to get together engineers and scientists who have dealt with the technical issues related to nano-science facilities to hear about the latest developments and challenges in this area. In particular we hoped to discuss topics related to stability and design.
