The measurement of momentum dispersion of a proton beam extracted from the accelerator U-70 by channeling has been carried out for the first time. The bending angle of the silicon crystal was 80 mrad. The beam parameters turned out to be as follows. The proton beam intensity was 107 per second when 1012 protons/sec hit the silicon crystal. The beam dispersion was Δp/p=0.13%. A background particle admixture in the beam was less than 0.03%.
