The possibilities of the extraction and collimation of a circulating beam by
a new method due to the reflection of particles in crystals with axial
orientation were experimentally investigated in the Fall-2010 run at the U_70
synchrotron. Such crystals have positive features, because the axial potential
is five times larger than the planar potential. It has been shown that the
collimation efficiency can reach 90% due to axial effects in the crystal.
Losses of the circulating beam on a collimator have been reduced by several
times; this makes it possible to suppress the muon jet near the steel
collimator of the circulating beam.Comment: 6 pages, 7 figure
