我们正在发展一种新的技术，将过渡边传感器（TES）应用于奇异原子，特别是K原子的X射线光谱学。为了证明这一开创性项目的可行性，基于TES的X射线探测器的性能在粒子加速器的π介子和K介子束环境中进行了评估。我们成功地观察到X射线从π碳原子的分辨率为7 eV的半高宽在6 keV。同样在kaon光束线上，我们证实TES光谱仪将能够在我们的第一次科学活动中实现我们的分辨率目标，6 eV，以测量来自kaonic-helium原子的X射线。
We are developing a new technique to apply transition-edge sensors (TESs) to X-ray spectroscopy of exotic atoms, especially of kaonic atoms. To demonstrate the feasibility of this pioneering project, performance of a TES-based X-ray detector was evaluated in pion- and kaon-beam environments at particle accelerators. We successfully observed X-rays from pionic-carbon atoms with a resolution as good as 7 eV FWHM at 6 keV. Also at a kaon beamline, we confirmed that the TES spectrometer will be able to achieve our resolution goal, 6 eV, in our first scientific campaign to measure X-rays from kaonic-helium atoms.
