A simple, reactor-based example instrument for MX diffraction is the instrument file [http://trac.mccode.org/browser/trunk/mcstas-comps/examples/templateNMX.instr templateNMX.instr] of the McStas distribution.

A snapshot of the contents dating from early 2015 is provided below and shows example use of
* The Single_crystal component
* SPLIT for boosting simulation stats

For the Rubredoxin.lau  system, the Single_crystal component has suggested to use a SPLIT repetition number of 43, corresponding to the average number of active reflections in the system . That chosen split value will give you an efficiency factor of 43 in production of reflected neutrons from the sample.
