Ok good to know

Great, that is even better.

I've noticed that this is still an open request. Is this more of a work than you initially thought?

We have some preliminary results for the following analyzer setup in the (+,+) geometry: Incoming beam: 2840+/- 0.015 eV Incoming divergence: +/-50urad Incoming beam size: 6x6mm2 First reflection: Ge(111) alpha=38.8deg,...

The crystals have a dimension of 150x15x10mm3 (LxWxH, 10mm thick) and where polished (5micron). We will try the 5x energy next month and do proper topography on their surface. That...

Correct no chemical etching. Our data does however show that if you simply select a smaller footprint (10mm instead of 100mm) on the Ge crystals the width is 85urad, the...

yes curved I 've tried and it can easily cause this. This is in principle can be fixed but I'd like to exclude the d-space variations.

Yes room temperature. In these conditions the thermal expansion of Ge is 5.9 x 10-6 K-1, about double the one for Silicon.

No problem and thanks for your help

I've tried it and it seems to work for the reflected intensity but it has no affect on the reflected angle. In principle if the d-space variations are fixed (i.e....
