The large scale US dark matter axion search

We describe the instrumentation and operations of the microwave cavity axio n detector presently taking data at Lawrence Livermore National Laboratory. This experiment, a collaboration of LLNL, MIT, Univ, of Florida, LBNL, Uni v, of Chicago, FNAL, and INR/Moscow, has been operating with greater than 9 0% live time since February 1996 with the objective of exploring the region from 0.3 to 3.0 GHz (1.2 to 12.4 mu eV) at greater than KSVZ sensitivity. In a companion paper (E. Daw) in these proceedings, the data analysis and f irst results will be described. (See also [1]).
