* the mosaicity may be anisotropic, so try to orient the crystal in the loop such that you can shoot along a different axis | * the mosaicity may be anisotropic, so try to orient the crystal in the loop such that you can shoot along a different axis | ||

* use a synchrotron beam (as it is less divergent than the usual home source, and the apparent mosaicity is the sum of the crystal mosaicity and the crossfire) | |||
* try smaller crystals (often growth faults lead to end of crystal growth) | |||
* shoot at parts of the crystals to find if there are good and bad parts (this requires a small beam) | |||
