在界面附近的中子应变扫描测量中，表面效应会导致不可接受的误差。单色中子源初级束的发散角和波长分布是造成这些巨大误差的主要原因。通过使用径向准直器来定义初级束横截面，可以产生均匀的束，这大大减少了表面效应。
The surface effect leads to unacceptable errors in neutron strain scanning measurements close to interfaces. The divergence and wavelength distribution in the primary beam from a monochromatic neutron source are mostly responsible for these huge errors. By using a radial collimator for the definition of the primary beam cross section a homogeneous beam can be produced which reduces the surface-effect drastically.
