The ALBA Synchrotron (Barcelona, Spain) has built MINERVA a new X-ray facility designed to support the development of the NewATHENA mission (Advanced Telescope for High Energy Astrophysics), whose objective is to observe and study energetic objects in space (accretion disk around black holes, large-scale structure, etc...). MINERVA is dedicated to assemble stacks manufactured by cosine into mirror modules (MM), building blocks of the NewATHENA optics. This new beamline is originally based on the X-ray parallel beam facility XPBF 2.0 at the Physikalisch-Technische Bundesanstalt (PTB at BESSY II) but also includes additional features on the scanning scheme to improve the characterization time of each MM produced. Interoperability between MINERVA and XPBF 2.0 is nonetheless preserved to boost the mass production of the MMs and characterize their performance. MINERVA is now in operation and has been funded by the European Space Agency (ESA) and the Spanish Ministry of Science and Innovation.
MINERVA is an X-ray beamline designed to contribute to the development of the ATHENA1, 14 mission (Advanced Telescope for High Energy Astrophysics) at the ALBA synchrotron2 (Barcelona, Spain). Originally based on the monochromatic pencil beam XPBF 2.0 at the Physikalisch-Technische Bundesanstalt (PTB at BESSY II), MINERVA will be furnished with the necessary equipment to produce and characterize the mirror modules (MM) of ATHENA by adjusting and assembling 4 SPO stacks together (manufactured by cosine measurement systems) 4,5. The construction of MINERVA is also an opportunity to bring some innovations in order to improve the characterization time of each MM produced6. Full interoperability with XPBF 2.0 is secured to allow operators to work on both beamlines the same way. The MINERVA project started in March 2020 and the last past months were dedicated to the definition, design, procurement, partial assembly and installation of the different beamline components. MINERVA is funded by the European Space Agency (ESA) and the Spanish Ministry of Science and Innovation and will be completed for operation at the turn 2022/2023.
The ALBA synchrotron (Barcelona, Spain) is building MINERVA a new X-ray beamline designed to support the development of the ATHENA mission (Advanced Telescope for High Energy Astrophysics). The beamline design is originally based on the monochromatic pencil beam XPBF 2.0 at the Physikalisch-Technische Bundesanstalt (PTB), at BESSY II. MINERVA will provide metrology capabilities to integrate stacks produced by cosine company into a mirror module (MM) and characterize them. It will provide photons with a fixed energy of 1.0 keV with a residual divergence below 1 × 1 arcsec2 rms. The beam dimensions at the mirror module is adjustable from 10 × 10 μm2 up to 8 × 8 mm2. Interoperability between MINERVA and XPBF 2.0 will be preserved in order to reinforce and boost the production and characterization of the mirror modules. MINERVA is funded by the European Space Agency (ESA) and the Spanish Ministry of Science and Innovation. Still in the detailed design phase, MINERVA will take 2 years to be completed for operation in 2022.
