本文报道了我们最近研制的一种带分束器的X射线干涉仪，并讨论了对某些天体的可能观测。X射线干涉仪由两个平面反射镜和一个平面分束器组成。设计并制作了分束器和反射镜样品。利用KEK-PF同步辐射光源对反射镜的反射率、分束器的反射率和透射率进行了测量，反射镜的测量结果与设计值基本一致，而分束器的反射率约为设计值的一半。利用这些测量值，我们估计所需的面积和观测时间，以获得天体的条纹信号。我们的结论是，使用非色散高光谱分辨率探测器的宽带干涉仪，如微量热计阵列，是未来发展的必要条件。
We report our recent activities for a development of a new X-ray interferometer with a beam splitter and discuss a possible observation of some celestial objects. The X-ray interferometer consists of two flat mirrors and one flat beam splitter. Samples of the beam splitter and the mirrors have been designed and fabricated. We measured the reflectivity of the mirrors and the reflectivity and transmission of the beam splitters with a synchrotron source at KEK-PF. Obtained results of the mirrors are roughly consistent with the design values, but the reflectivity of the beam splitter is roughly half of the design value. Using these measured values, we estimated required area and observation-time to obtain fringe signals of celestial objects. We concluded that a broad-band interferometer using non-dispersive high spectral resolution detector, such as the micro-calorimeter array, is essential for the future development.
