First beam on SIKA

The SIKA cold-neutron 3-axis spectrometer, which is operated by the NSRRC, has taken its first neutron scattering patterns.  A diffraction pattern of a common standard Ni was first measured in diffraction mode before the 3rd axis was added to produce an inelastic neutron scattering spectrum of a crystal-field excitation in PrFeO3

A fixed incident energy of 5.11 meV was used and the spectrum shows a scan of the final energy, with the excitation at an energy transfer of around 2 meV.
