[mcstas-users] Component Monochromator-reflect

Dear Thierry,

I am trying to make calculations with mosaic crystals. The following paper states that a new component, called Monochormator-reflect, was introduced in order to overcome some limitations of Monochromator_curved:

L. Alianelli, N. Wilson, K.H. Andersen, M. Sánchez del Rı́o, R. Felici, A method for detailed simulations of neutron diffraction from imperfect crystals, Nucl. Instr. Meth A 529 (2004) 231–233.

Does anyone know what this became ? Was it included into another more sophisticated component that can be used to simulate monochromators, like Single_crystal ?

I do have a copy of the said component component somewhere, but could not locate it at first glance. I am also sure both Erik and Emmanuel has a copy. I am however also sure that it will not work “out of the box”. :)

( The reason that the component never made it into the official McStas release was in a way simple:
 It relied on an inputfile that was prepared using an IDL procedure-code, which we thought was a very nasty dependency…)

What specific advanced feature(s) are you looking for? We do have a number of other good alternatives, e.g. Single_crystal or NCrystal.


Best,
Peter
