Institute of Biological Sciences: X-ray Optics Laboratory

Services:

 

1. design, manufacture and implementation of glass and metallic X-ray capillaries for micro-beam formation for techniques such as XRF, XPS, ARPES.

2. manufacture of X-ray capillaries for specific application, with regard to the specific light source.

3. deposition of layers and bilayers by magnetron sputtering and effusion cell deposition with strictly controlled thickness on flat substrates (silicon, glass, plastics, etc.) and those of unusual shapes such as thin wires.

4. full characterization of surface morphology (AFM, optical profilometer, mechanical profilometer) and the chemical composition and thickness of layers/dual layers (optical, mechanical, AFM, TOF-SIMS profilometer).

5. deposition of metallic layers: copper, nickel, gold by electro-deposition in a highly controlled manner (thickness, tensile stress, morphology).

6. deposition of layers on non-standard samples: thin wires, rollers, items with non-standard shapes.

7. morphological characterization of surfaces in the nanoscale using an atomic force microscope equipped with an efficient automated measuring table for measuring large samples.

8. characterization of organic layers and multilayers using time-of-flight detector mass spectometry (TOF-SIMS).
