FANS – Specifications

Energy transfer range 5 - 250 meV (Click on these links to see figures)

Resolution ~1.1 meV at low energies (determined by the filter cutoff); resolution at high energies given by the performance of monochromator Energy resolution

Q range

Detector coverage 9% of 4 π

In phase-II Double focusing monochromators will provide an incident flux of almost 10⁷ n/cm².s ( a gain of ~4 over phase I) Estimated incident flux

Incident beam cross-section 30 mm x 70 mm

Minimum sample mass 10 mg for a hydrocarbon sample
