Phase-matching of multiple-cavity detectors for dark matter axion search
Conventional axion dark matter search experiments employ cylindrical
microwave cavities immersed in a solenoidal magnetic field. Exploring higher
frequency regions requires smaller size cavities as the TM010 resonant
frequencies scale inversely with cavity radius. One intuitive way to make
efficient use of a given magnet volume, and thereby to increase the
experimental sensitivity, is to bundle multiple cavities together and combine
their individual outputs ensuring phase-matching of the coherent axion signal.
We perform an extensive study for realistic design of a phase-matching
mechanism for multiple-cavity systems and demonstrate its experimental
feasibility using a double-cavity system.Comment: 5 pages, 2 figures, 1 tabl
