Polarized Proton Beam Acceleration at the Nuclotron with the Use of the Solenoid Siberian Snake

摘要

The possibility of polarized protons acceleration up to 6 GeV at the Nuclotron is analyzed. Proton beam acceleration by application of full and partial Siberian Snakes are considered. Compensation of the betatron coupling introduced by the solenoids is done by a compact insert of quadrupoles with a certain symmetry of their tilt angles around the orbit direction. Such a scheme has a shorter total length of the quadrupoles than the known compensation schemes. The Snakes installed within one, 3.2 m long, or two, 2 × 3.2 m long, straight sections of the Nuclotron lattice are considered.
