Super-Polished X-ray Kirkpatrick Baez optical systems for the SPB-Instrument
Delivery of a Super-Polished X-ray Kirkpatrick Baez optical systems for the Single Particle, Clusters and Biomolecules (SPB) Instrument including the production of all mirrors, mechanical components and vacuum chambers needed for the focusing systems as well as the necessary design work, metrology of mirrors, testing and documentation.
The system consists of two different sub systems: one to provide a 100 nm scale focus and a second to provide a micron scale focus. The 100 nm scale focus consists of two (2) super-polished X-ray KB mirrors: one for horizontal focusing and one for vertical focusing. The micron scale focus consists of four (4) super-polished X-ray KB mirrors: a focusing pair for the KB and two additional flat mirrors to steer the European XFEL due to the long focal length.
Challenges of this project are the extremely tight tolerances for the slope error and profile error (2 nm peak-to-valley) of the 1 meter long mirrors, which all have to be provided also with a cooling system. This has to be matched by a rigid design of the mounts and mirror vessels, which should not exceed vibration levels of 20 nrad rms.
Special attention has to be paid to the UHV compatibility (1E-9 mbar or better hydrocarbon-free vacuum) and the particle-free requirements (ISO5) concerning the design and assembly of the vacuum chambers.
