This plot shows the projected sensitivity of ADMX after the dilution
refrigerator and second channel (currently under construction) are
added. ADMX will be sensitive to even the most pessimistically coupled
dark matter axions in the range 1ueV to 10ueV in the near future.
Targets for high frequency R&D are also shown.
For any questions about the experiment or for more information please email Professor Leslie Rosenberg at ljrosenberg@phys.washington.edu, or call (206) 221-5856.
