We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it is a geometrically frustrated magnetic Fe3+ ions arranged on an anisotropic triangular lattice arranged in chains which loosely form a honey-comb type lattice. Second, susceptibility measurements indicate a broad peak at high temperatures (~250 K) indicating low-dimensional spin correlations. Third, the powder pattern only shows that a fraction of the spins are ordered equally on both sites and that there is missing elastic spectral weight.
