Abstract

The BEaTriX (Beam Expander Testing X-ray) facility has completed the commissioning phase. This unique compact facility – that occupies an area of 8 x 14 m2 - provides a large (170 mm × 60 mm) collimated (< 2.5 arcsec) monochromatic beam at the energy of 4.51 keV. Its concept is based on the combination of a microfocus X-ray source, a parabolic mirror, and a set of silicon crystals, one of which is asymmetrically cut with respect to the lattice planes. The tests have proven the BEaTriX capability to perform the acceptance tests for Point Spread Function and Effective Area of the NewAthena Silicon Pore Optics Mirror Modules (MM) with a 3 MM/day throughput. The second BEaTriX beamline at the X-ray of 1.49 keV is currently being developed. The optomechanical design, and simulation of alignment tolerances have been completed. The parabolic mirror is being polished at INAF-OAB, on the basis of the experience matured with producing the parabolic mirror for the 4.51 keV beam line. The crystals for the monochromator (Quartz 10-10) and the beam expander (ADP 101) are being procured. Differently from the 4.51 keV beam line, all three crystals for the 1.49 keV are asymmetrically cut, as a special design has been adopted to guarantee the specifications. Owing to the good results obtained by BEaTriX at the INAF labs in Italy, a feasibility study is also ongoing to replicate the facility with a similar design at cosine B.V. in The Netherlands (where the MMs will be produced) for measuring the MMs SPO at 1.49 and 6.4 keV before and after the vibrational tests.
