Abstract

An experiment proposed to search for dark-matter axions in the mass range 0.6-16 mu eV is described. The method is based on the Primakoff conversion of axions into monochromatic microwave photons inside a tunable microwave cavity in a large-volume high-field magnet. This proposal capitalizes on the availability of two Axicell magnets from the MFTF-B fusion machine at Lawrence Livermore National Laboratory. Assuming a local dark-matter density in axions of rho /sub a/=0.3 GeV/cm/sup 3/, the axion would be found or ruled out at the 97% c.l. in the above mass range in 48 months.<>
