Title: "The ADMX Axion Search" 

Abstract: Axions are light pseudoscalar particles that, if they exist, 
may solve the strong CP problem of particle physics and simultaneously 
explain the dark matter problem. They are physically just as well 
motivated as weakly interacting massive particles (WIMPs) as a 
candidate for dark matter, though they have received less attention 
from experimentalists.  I will report on the status of the ADMX experiment, 
which uses copper plated cryogenic tunable electromagnetic resonators to 
search for dark matter axions. The experiment has been running since 1994, 
and is preparing for a new run with ultra low noise RF squid electronics 
and a dilution refrigerator.
