摘要
BEaTriX(波束扩展测试x射线)设备现在在意大利梅里特的国际天文研究所(inaf - observatorio Astronomico Brera)运行。该设施是专门为ATHENA硅孔光学(SPO)镜像模块(MM)的x射线验收测试(PSF和有效面积)而设计和建造的。独特的设置创造了一个平行的、单色的、大的x射线束，充分照亮mm的光圈，在雅典娜12米的焦距处产生图像。这可以通过微聚焦x射线源，然后是一系列光学元件(抛物面镜，2通道切割单色器和不对称硅晶体)，能够将x射线束扩展到6厘米× 17厘米的尺寸，剩余散度为1.5弧秒(垂直)× 2.5弧秒(水平)。本文报道了4.5 keV光束线的调试，以及用反射镜模块获得的第一束光。
X-ray tests of the ATHENA mirror modules in BEaTriX: from design to reality
The BEaTriX (Beam Expander Testing X-ray) facility is now operative at the INAF-Osservatorio Astronomico Brera (Merate, Italy). This facility has been specifically designed and built for the X-ray acceptance tests (PSF and Effective Area) of the ATHENA Silicon Pore Optics (SPO) Mirror Modules (MM). The unique setup creates a parallel, monochromatic, large X-ray beam, that fully illuminates the aperture of the MMs, generating an image at the ATHENA focal length of 12 m. This is made possible by a microfocus X-ray source followed by a chain of optical components (a paraboloidal mirror, 2 channel cut monochromators, and an asymmetric silicon crystal) able to expand the X-ray beam to a 6 cm × 17 cm size with a residual divergence of 1.5 arcsec (vertical) × 2.5 arcsec (horizontal). This paper reports the commissioning of the 4.5 keV beam line, and the first light obtained with a Mirror Module.
