Sans_spheres
ComponentSample for use in a SANS instrument, models hard, mono disperse spheres in thin solution. The shape of the sample may be a cylinder of given radius or a box with dimensions xwidth, yheight, zthick. qmax defines a cutoff in q. Example: Sans_spheres(R = 100, Phi = 1e-3, Delta_rho = 0.6, sigma_a = 50, qmax = 0.3 ,xwidth=0.01, yheight=0.01, zthick=0.005) %BUGS This component does NOT simulate absolute intensities. This latter depends on the detector parameters.
