“…From the simulations and experimental measurements, the pitch rotations of the optical elements and the yaw position of the paraboloidal mirror are the most critical. 11,12 The alignment and qualification of the BEaTriX X-ray beam created by the optical chain are performed with different tools and detectors.…”

In the framework of NewATHENA x-ray space telescope, BEaTriX (Beam Expander Testing X-ray) is the novel ground support equipment designed to perform the Silicon Pore Optics Mirror Modules (SPO MMs) acceptance tests in terms of point spread function and effective area. As of today, the facility built at INAF-Brera Astronomical Observatory in Merate has a first operative beamline at the energy of 4.51 keV. The 170 mm × 60 mm x-ray beam, created by an innovative optical setup, is able to fully illuminate a complete SPO MM in a single exposure with a parallel and monochromatic X-ray beam. The optical chain includes a paraboloidal mirror, with an x-ray source in its focus, that collimates and expands vertically the beam, a monochromatic stage composed by a set of symmetrically cut silicon crystals (the Channel Cut Crystals), and an asymmetrically cut silicon crystal (the Beam Expander) that expands the beam horizontally. To achieve the expected x-ray beam quality in terms of collimation, number of photons and uniformity, the BEaTriX optical components need to be properly aligned. The result of several measurements confirms the theoretical predictions on the behavior of each optical element. This paper describes the work performed to quantify the x-ray beam properties with the adoption of different types of detectors, and alignment sequence, providing the outlook for further optimizations.

“…The characterization of the X-ray beam was performed in size, collimation, intensity and uniformity. To reach the desired beam, a careful alignment procedure was developed and implemented (see [20]). The source was powered at 30kV/200µA, which was measured to produce 6.34×10 11 ph/s/sr [19].…”

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.
