欧洲核子研究中心的轴子太阳望远镜已经完成了对含有氦缓冲气体的太阳轴子的搜索，搜索范围为0.64 eV至1.17 eV。这就关闭了宇宙学热暗物质极限的差距，实际上与之重叠。当磁铁指向太阳时，没有多余的x射线，我们设定了一个典型的轴子-光子耦合上限，即在95% C. L.时，gaγ = 3.3 × 10（-10）GeV（-1），精确值取决于压力设置。未来的直接太阳轴子搜索将侧重于提高对较小gaγ值的灵敏度，例如目前正在讨论的下一代日光镜国际轴子天文台。
The CERN Axion Solar Telescope has finished its search for solar axions with (3)He buffer gas, covering the search range 0.64 eV ≲ ma ≲ 1.17 eV. This closes the gap to the cosmological hot dark matter limit and actually overlaps with it. From the absence of excess x rays when the magnet was pointing to the Sun we set a typical upper limit on the axion-photon coupling of gaγ ≲ 3.3 × 10(-10) GeV(-1) at 95% C.L., with the exact value depending on the pressure setting. Future direct solar axion searches will focus on increasing the sensitivity to smaller values of gaγ, for example by the currently discussed next generation helioscope International AXion Observatory.
