In the problem on motion of magnetized relativistic electrons in a cylindrical channel with the radius comparable with characteristic Larmor radius of the electrons, a distribution of electrons with arbitrary initial angular spread absorbed in the channel wall along its axis is found. The solution is obtained by 3D modelling taking into account the reflection of electrons from the cylindrical surface of the channel. Basing on the received solution the multichannel detector of the electron angular spread in the form of sequential absorbing collimators with gradually decreasing diameter is constructed and tested in a real experiment. Mathematical procedure to find the angular distribution function of the electron velocities from the measurements of the collimator currents is described. Keywords:
