SasView_model Component
Sample for use in SANS instruments. The models describe mono disperse particles in thin solution. The sample geometry may have the shape:
Shape: - A filled box with dimensions xwidth, yheight and zdepth.
- A cylinder with dimensions radius and yheight.
- A filled sphere given by radius.
These parameters are mutually exclusive.
Example using spheres in thin solution, with radius=200 AA and a delta_sld=0.6 fm/AA^3:
SasView_model(model_index=47, model_scale=1.0, model_pars={1, 7, 200}, model_abs=0.0, xwidth=0.01, yheight=0.01, zdepth=0.005,)
The algorithm of this component requires use of the ISO C standard c99. You could use MCSTAS_CFLAGS like MCSTAS_CFLAGS = -std=c99 -g -O2 -lm.
Or, add the flag "-std=c99" to "C flags" in the mcgui or mcgui-py config.
The list of scattering models in SasView is called sasmodels. The list of McStas available SasView sasmodels are found in the table below.
A few models may require manual documentation lookup using the above link to the SasView site.
McStas does currently not support multiplication of formfactor models with structure factor models.
The 2D scattering scattering kernels are denoted by modelname_xy. I.e. to evalulate scattering from aligned cylinders use model_index=10 to use cylinder_xy.
