摘要:
我们首次开展了将RADES-BabyIAXO腔体用作高频引力波(HFGWs)探测器的分析研究。我们具体讨论了适用于不同HFGW频段的两种配置:1号腔体主要在252.8-333.2 MHz频段具备灵敏度,2号腔体工作在2.504-3.402 GHz频段,是1号腔体的缩小版本。研究发现1号腔体对HFGW的应变灵敏度可达h₁~10⁻²¹量级,2号腔体可达h₂~10⁻²⁰量级。这些是RADES-BabyIAXO腔体作为HFGW探测器的最优性能估算,表明该装置可同时在轴子物理和HFGW研究领域取得突破性成果。
英文摘要:
We present the first analysis using RADES-BabyIAXO cavities as detectors of high-frequency gravitational waves (HFGWs). In particular, we discuss two configurations for distinct frequency ranges of HFGWs: Cavity 1, mostly sensitive at a frequency range of 252.8 - 333.2 MHz, and Cavity 2, at 2.504 - 3.402 GHz, which is a scaled down version of Cavity 1. We find that Cavity 1 will reach sensitivity to strains of the HFGWs of order $h_1\sim 10^{-21}$, while Cavity 2 will reach $h_2\sim 10^{-20}$. These represent the best estimations of the RADES-BabyIAXO cavities as HFGWs detectors, showing how this set-up can produce groundbreaking results in axion physics and HFGWs simultaneously.
