I14 Hard X-ray Nanoprobe Workshop

The objective of this workshop was to describe the potential of the I14 HXNP beamline to the UK user community and to define more clearly their requirements.

I14 Hard X-ray Nanoprobe Workshop

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 late 2016/early 2017.

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 (6-20 KeV)
  • Raster scanning capability for fast acquisition and increased sample area coverage.
  • Standard specimen environments compatible with high resolution imaging and including a cryogenic capability to allow imaging of radiation-sensitive samples.
  • XANES mapping capability
  • Simple data acquisition software with a strong emphasis on fast post acquisition data processing

The range of potential applications is large, including materials science (e.g. new polymers, magnetic and nano-structured materials), earth and environmental science and geochemistry (e.g., aerosols, minerals, sediments, soils and bio-remediation); chemistry (including new energy sources), biological, biotechnological and biomedical science (new biomaterials, elemental imaging of cells).

The objective of this workshop was to describe the potential of the I14 HXNP beamline to the UK user community and to define more clearly their requirements. At the end of the workshop, the UK user community as well as the working group should have a clear vision of the I14 HXNP beamline and its scientific case and conceptual design. The workshop was combined with an initial meeting of the members of the I14 User Working Group.

The meeting was limited to about 40 persons.
