Autor: Yu. N. Filatov, A. M. Kondratenko, M. A. Kondratenko, Ya. S. Derbenev, V. S. Morozov, A. V. Butenko, E. M. Syresin, E. D. Tsyplakov
Publikováno v: European Physical Journal C: Particles and Fields, Vol 81, Iss 11, Pp 1-9 (2021)
Abstract Hadron polarization control schemes for Spin Transparent (ST) synchrotrons are analyzed. The spin dynamics and beam polarization in such synchrotrons are controlled by spin navigators (SN) which are special small insertions of weak magnetic

Publikováno v: European Physical Journal C: Particles and Fields, Vol 80, Iss 8, Pp 1-11 (2020)
Abstract Small perturbative fields in a synchrotron influence both the spin and orbital motion of a stored beam. Their effect on the beam polarization consists of two contributions, a direct kick and an effect of the ring lattice due to orbit perturb

We consider the capability of flexible spin-transparent polarization control and manipulation in conventional synchrotrons at integer spin resonances by means of spin navigators. The latter are designed as a couple of small solenoids separated by a c

Publikováno v: Physical Review Accelerators and Beams, Vol 20, Iss 9, p 091003 (2017)
Solenoid Siberian snakes have successfully maintained polarization in particle rings below 1 GeV, but never in multi-GeV rings, because the spin rotation by a solenoid is inversely proportional to the beam momentum. High energy rings, such as Brookha

Publikováno v: JETP Letters. 116:413-419
A spin navigator based on correcting dipoles has been proposed to manipulate the directions of protons spins in experiments at the Nuclotron synchrotron (JINR, Dubna). The polarization is controlled by means of the controllable distortion of the beam
