论文摘要
我们通过在超导射频(SRF)圆柱腔内的两个电磁模式来解决大规模轴突样颗粒的生产。我们详细讨论泵模式和空腔设计的选择。我们在数值上计算各种腔模式和广泛的轴突质量的轴突场的时间平均能量密度。这使我们能够估计腔内轴突产生的最佳条件。此外,我们考虑由筛选的射频腔中产生的轴向场引发的光子再生过程,并在参数空间$(g_ {aγγ},\ m_a)$中得出约束,以用于泵模式的不同选择。
We address production of massive axion-like particles by two electromagnetic modes inside a superconducting radio-frequency (SRF) cylindrical cavity. We discuss in detail the choice of pump modes and cavity design. We numerically compute time-averaged energy density of produced axion field for various cavity modes and wide range of axion masses. This allows us to estimate optimal conditions for axion production within a cavity. In addition, we consider photon regeneration process initiated by produced axion field in a screened radio-frequency cavity and derive constraints in parameter space $(g_{aγγ},\ m_a)$ for different choice of pump modes.
