A Dark Matter Hurricane: Measuring the S1 Stream with Dark Matter Detectors [PDF]
, 2018 The recently discovered S1 stream passes through the Solar neighbourhood on a low inclination, counter-rotating orbit. The progenitor of S1 is a dwarf galaxy with a total mass comparable to the present-day Fornax dwarf spheroidal, so the stream is ...

Analytical considerations for optimal axion haloscope design
Journal of Physics G: Nuclear and Particle Physics, 2022 Abstract The cavity haloscope provides a highly sensitive method to search for dark matter axions in the microwave regime. Experimental attempts to enhance the sensitivity have focused on improving major aspects, such as producing strong magnetic fields, increasing cavity quality factors, and achieving lowest possible noise ...

Axion haloscope signal power from reciprocity
Journal of Cosmology and Astroparticle Physics, 2023 Abstract Axion haloscopes search for dark matter axions from the galactic halo, most commonly by measuring a power excess sourced by the axion effective current density. Constraining axion parameters from detection or lack thereof requires estimating the expected signal power. Often, this is done by studying the response of the haloscope

Taiwan axion search experiment with haloscope: Designs and operations
Review of Scientific Instruments, 2022 We report on a holoscope axion search experiment near 19.6 µeV from the Taiwan Axion Search Experiment with Haloscope collaboration. This experiment is carried out via a frequency-tunable cavity detector with a volume V = 0.234 liter in a magnetic field B0 = 8 T.

Symmetry Breaking in Haloscope Microwave Cavities [PDF]
, 2018 Axion haloscope detectors use microwave cavities permeated by a magnetic field to resonate photons that are converted from axions due to the inverse Primakoff effect. The sensitivity of a detector is proportional to the form factor of the cavity's search mode.
