我们总结了最近的进展,轴子纵向等离子体晕镜(ALPHA)联盟,一个新的实验合作,建立一个等离子体晕镜寻找轴子和暗光子。等离子体晕圈仪是一种探测光暗物质共振转换为光子的新方法。阿尔法将在近十年的参数空间中对QCD轴子敏感,可能发现暗物质并解决强问题。与传统的腔体天体观测器不同,传统的腔体天体观测器通常在体积上受到暗物质的康普顿波长的限制,等离子体天体观测器使用金属丝超材料来创建可调谐的人工等离子体频率,将光的波长与康普顿波长解耦,并允许更强的信号。我们发展的理论基础等离子体haloscope和讨论最近的实验进展。最后,我们概述了一个基线设计的ALPHA和显示,一个全面的实验可以发现QCD轴子在近十年的参数空间。
We summarize the recent progress of the Axion Longitudinal Plasma Haloscope (ALPHA) Consortium, a new experimental collaboration to build a plasma haloscope to search for axions and dark photons. The plasma haloscope is a novel method for the detection of the resonant conversion of light dark matter to photons. ALPHA will be sensitive to QCD axions over almost a decade of parameter space, potentially discovering dark matter and resolving the strongproblem. Unlike traditional cavity haloscopes, which are generally limited in volume by the Compton wavelength of the dark matter, plasma haloscopes use a wire metamaterial to create a tuneable artificial plasma frequency, decoupling the wavelength of light from the Compton wavelength and allowing for much stronger signals. We develop the theoretical foundations of plasma haloscopes and discuss recent experimental progress. Finally, we outline a baseline design for ALPHA and show that a full-scale experiment could discover QCD axions over almost a decade of parameter space.
