About us

The CORDE Atom Scattering Facility’s measurement capability is unique globally – no other technique exists which can provide this kind of information in these regimes.  

  • A wide range of measurements is possible, although the main focus is on helium spin-echo (HeSE) dynamics measurements and scanning helium microscopy (SHeM).  
  • HeSE measurements enable surface diffusion, energy barriers, correlated motion, and atomic-scale friction, etc., to be studied.
  • HeSE allows the ability to map out the dispersion and lifetime of phonons at surfaces and in 2D materials. 
  • SHeM enables ultra-delicate microscopy and spot profile diffractive analysis suitable for 2D materials, insulators, polymers, bio-materials, etc., with unique contrast and without the possibility of sample damage, charging, or any need for coating.
