23. SERAPH: Wavelike Dark Matter Searches with SRF Cavities

Raphael Cervantes

7/6/23, 4:35 PM

Haloscopes consisting of a microwave cavity with a high quality factor (Q) connected to low-noise electronics have been deployed to detect wavelike axions and dark photons. But the dark matter mass is unknown, so haloscopes must be tunable to search through the photon coupling vs. mass parameter space. Therefore, the scan rate for haloscope experiments is a crucial figure of merit and is...

28. High-temperature superconducting cavities: current progress and future plans for axion searches at CAPP

Dr Danho Ahn (IBS-CAPP)

7/6/23, 4:55 PM

Superconducting radiofrequency technology has been essential for advancing the performance in particle physics experiments over the past decades. In particular, axion haloscopes require high-quality factor (Q) superconducting cavities working in multi-tesla magnetic fields to enhance scanning speeds, which can be accomplished using high-temperature superconducting (HTS) tapes....

83. Searching for Low-Mass Axions using Resonant Upconversion

Catriona Thomson (Univeristy of Western Australia)

We present new results of a room temperature resonant AC haloscope, which searches for axions via photon upconversion. Traditional haloscopes require a strong applied DC magnetic background field surrounding the haloscope cavity resonator, the resonant frequency of which is limited by available bore dimensions. UPLOAD, the UPconversion Low-Noise Oscillator Axion Detection experiment, replaces...
