High throughput spectrometer

We are seeking a technology provider for a spectrometer specifically designed for nonlinear soft X-ray spectroscopy and scattering experiments, including pump-probe resonant inelastic X-ray scattering. The spectrometer must feature a grating chamber accommodating up to three gratings and a detector chamber with an interchangeable, position-sensitive X-ray detector, as well as an alignment module. Gratings and detector are not part of the project. Key specifications include: - Grating deformation-free positioning with few micrometer / tens microradian accuracy and motorised rotation with sub-microradian accuracy. - Detector chamber motorised movement with few micrometers over few hundreds millimeters accuracy. - Precise alignment of the grating and detector axes separated by about 1.5 m, with overall alignment accuracy within 0.1 mm and parallelism within 1 mrad. - Accommodation of additional components as masks, filters, slits, imagers, movable with micrometer accuracy. - Motorised alignment module to bring the spectrometer in the beam position. - The spectrometer shall be mobile and consist of two modules, each of them shall weight <1 ton. - The spectrometer should effectively minimize vibrational effects within a frequency range of 0.01 Hz to 100 Hz. In operational conditions, the mechanical structure should exhibit a vibrational transfer function better than 10. - Vacuum components must achieve a base pressure of ≤1 x 10^-8 mbar in both the grating chamber and the bellows section. - The provider must have documented experience with production of soft X-Ray grating spectrometers or monochromators of similar size and complexity.
