The fully operational prototype of a rotational velocity selector for neutron beam monochromation has been tested and the results compared to the theoretical characteristics (output wavelength, transmission and selectivity with respect to velocity and horizontal tilt angle of the multiblade rotor system). The minimum of the selected central wavelength is 2.5 Å in the current construction. Measurements are performed on a cold neutron beam at the Budapest Neutron Centre by energy-resolved pinhole beam imaging, using a 2D position-sensitive detector in time-of-flight regime. Thus, the effects of the incoming beam divergence are also evaluated.
