View source for Simulation Project SANS-2: Resolution of the SANS instrument

A thin sample that scatters the beam with a fixed value of \(|{\bf q}|\) can be used to simulate the \(q\)-resolution of the instrument. Argue that this is the case and that the component <tt>Powder1</tt> can be used for this purpose.

Insert this component and simulate the results for \(L_{\rm c} = L_{\rm d} = 6\) m for two values of \(q\), representative for the \(q\)-range of the instrument. Perform the same simulations for \(L_{\rm c} = L_{\rm d} = 3\) m. Comment on the results.
