论文摘要
振荡的光轴场被称为波暗物质。我们提出了使用电磁磁铁设施的轴突暗物质引起的狭窄带电信号的LC谐音增强的检测。我们为信号电场提供完整的3D电磁模拟结果。谐振LC电路的高$ q $因子增强了电信号，然后通过最先进的低温电气传输测量技术进行扩增和检测。低温放大器噪声是拟议检测系统中的主要噪声源。我们估计检测系统对轴线暗物质具有有希望的敏感性，质量低于$ 10^{-6} $ eV。投影敏感性随磁场的大小而改善，电信号测量可能对量子染色体动力学（QCD）轴，并使用$ g_ {aγ} \ sim 10^{ - 16} $ gev $^{ - 16} $ gev $^{ - 1} $ about $ m_a \ sim \ sim \ sim \ sim \ sim \ sim 10^{ - 8} $ ev，scair a multer a multer a a multer a a multe a a ime-abore。该极限约为宇宙射线当前约束的五个数量级。
The oscillating light axion field is known as wave dark matter. We propose an LC-resonance enhanced detection of the narrow band electric signals induced by the axion dark matter using a solenoid magnet facility. We provide full 3D electromagnetic simulation results for the signal electric field. The electric signal is enhanced by the high $Q$-factor of a resonant LC circuit and then amplified and detected by the state-of-the-art cryogenic electrical transport measurement technique. The cryogenic amplifier noise is the dominant noise source in the proposed detection system. We estimate that the detection system can have a promising sensitivity to axion dark matter with mass below $10^{-6}$ eV. The projected sensitivities improve with the size of the magnetic field, and the electric signal measurement can be potentially sensitive to the quantum chromodynamics (QCD) axion with $g_{aγ} \sim 10^{-16}$ GeV$^{-1}$ around $m_a \sim 10^{-8}$eV, with a multi-meter scale magnetized region. This limit is around five orders of magnitude below the current constraint from the cosmic rays.
