Description

DALI (Dark-photons & Axion-Like particles Interferometer) is a next-generation haloscope experiment targeting the 25–250 μeV mass range in the search for axion dark matter. It introduces a novel experimental approach based on a magnetized phased array (MPA) architecture and a tunable resonator, offering significant advantages over conventional designs.
This presentation will outline the DALI concept and its scientific objectives, with a focus on the development and testing of a proof-of-principle prototype. We intend to present initial experimental data, performance benchmarks, and the optical design and simulation results for the full antenna array — a critical component for achieving broadband sensitivity across the targeted mass range.
The talk will highlight both the conceptual innovation and the current experimental progress of the DALI program and discuss its potential contribution to the direct detection of axion dark matter in a largely unexplored spectral range.
