Design Blueprint: A Network of Axion Haloscopes: Scan Rate and Frequency Coverage Computed from the Cavity Conversion Equation

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24150246): A network of four axion haloscopes is designed from the scan-rate equation that governs the search for axion dark matter. Each instrument — an 8 T magnet, a 0.20 cubic metre cavity of loaded quality factor 80,000 and a quantum-limited receiver at 0.35 K system temperature — scans at 0.33 GHz per year at the benchmark coupling. Four instruments on adjacent bands cover 1 to 8 GHz in 5.3 years. The n Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
