The Sans_spheres Component

Sample for Small Angle Neutron Scattering - hard spheres in thin solution, mono disperse.

Identification

Description

Sample 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)

Input parameters

Parameters in boldface are required; the others are optional.
