abstract = {{For the development of boron neutron capture therapy - an accelerator source of epithermal neutrons has been proposed and created at the Budker Institute of Nuclear Physics (Novosibirsk, Russia). For future therapy it is necessary to ensure the transportation of a proton beam in a high-energy beam line at a distance of 10 meters. For this purpose, using a movable diaphragm with a diameter of 1 mm, mounted on a three-dimensional vacuum manipulator, and a wire scanner, the phase portrait of the proton beam was measured. The software for remote control of the movable diaphragm and data processing of the wire scanner was developed. An algorithm for processing a series of measurements was developed to reconstruct the image of the phase portrait of the beam and calculate the emittance. This work describes in detail the features of the measuring devices, control algorithms and data processing. An experiment was carried out to measure the phase portrait and emittance of a proton beam with an energy of 2 MeV and a current of up to 3 mA. A beam of neutral particles was also measured. The effect of a bending magnet on the focusing and emittance of the beam is studied. The invariant normalized emittances calculated from the measured phase portraits make it possible to assert that the beam can be transported over distances of about 10 meters without changes in the current geometry of the high-energy beam line.}},
