MACS Total Flux at different energies.

MACS Total Flux at different energies. The neutron fluxes below 5 meV were taken with a Be filter placed after the source. The flux above 5 mev were taken withot the Be filter and were l/2 corrected.

DXAL and SPINS integrated intensity comparison graphs.

The Integrated intensity is simmilar for both SPINS and the DXAL. Multiple scattering effects are more prominent on the DXAL due to the double crystal analyzer.
