The collimation in a typical SANS instrument is performed by two pinholes separated by a distance. Consider a circular pinhole (made from an absorbing material), \(d=8\) mm, placed in the centre of a neutron beam and an identical circular pinhole a distance \(L=6\) m further down the beam. Calculate the maximal divergence in the \(x\) and \(y\) direction.
