A Bonse-Hart camera was installed in order to examine the performance of the X-ray beam and its source for this type of experiments. The results show that excellent data can be obtained very fast. They belong to a scattering vector range which is partially covered by visible light scattering experiments. The limiting problem is caused by diffuse scattering from the channel-cut crystals (up to 5 reflections) but according to our results it should be possible to decrease this effect substantially by using a still higher number of reflections while still maintaining unprecedentedly high count rates and dynamic range due to the very bright source. |
