Specifications


Spatial resolution
The microprobe is formed using Schwartzschild objectives with multilayers. Two can be installed in UHV at the same time. We have available 27 eV, 74 eV and 95 eV objectives.

   Flux and line width on the sample  (monochromator slit 100 µm)
 
27 eV 2x1010 photons sec -1 5 meV
74 eV 1.5x1011 photons sec -1 70 meV
95 eV 2x1011 photons sec -1 100 meV

    Long range background

We use mostly 27 eV with less than 1 % Background and 74 eV with less than 25 % background.

   Microprobe size

 

    Focal depth

Because of large (0.2) numeric apertire the focal depth is small. We need to focus with precision of approximately 2 µm.
