Abstract
The cold neutron transmission through a monolithic polycapillary lens is studied by scanning a pinhole beam across the entrance cross sectio n of the lens. The relative transmission as a function of bending radi us of a tapered channel is obtained. The results are explained in term s of a reduced critical angle for total reflection for the tapered cha nnels. A technique for qualitative examination of monolithic lenses is proposed.
