An experiment is described to detect dark matter axions trapped in the halo
of our galaxy. Galactic axions are converted into microwave photons via the
Primakoff effect in a static background field provided by a superconducting
magnet. The photons are collected in a high Q microwave cavity and detected by
a low noise receiver. The axion mass range accessible by this experiment is
1.3-13 micro-eV. The expected sensitivity will be roughly 50 times greater than
achieved by previous experiments in this mass range. The assembly of the
detector is well under way at LLNL and data taking will start in mid-1995.Comment: Postscript, 6 pages, 4 figures; submitted to proceedings of: XXXth
