GigaBREAD: Reflector Design, Simulations, and Cryomagnet Integration for Broadband Axion Detection
ORAL
Abstract
GigaBREAD, the Gigahertz Broadband Reflector Experiment for Axion Detection, utilizes a parabolic reflector housed in a cylindrical barrel to focus axion-induced photons onto a high-sensitivity receiver. This setup enables searches for dark photon and axion-like dark matter in the 10-15 GHz microwave range, corresponding to masses of 41.4-62 μeV. This talk will address key design considerations for the parabolic reflector to achieve efficient photon conversion without resonant tuning, electromagnetic simulations evaluating magnet quench resilience and signal fidelity, thermal simulations ensuring cryogenic stability in dilution fridge setups to suppress noise, and an overview of experimental progress towards enhancing GigaBREAD's reach into the axion parameter space.
