Acceleration of polarized electrons in a weak-focusing synchrotron

A design of the system for producing polarized electrons and photons on the Tomsk synchrotron is discussed. The method is based on interactions between electrons and polarized hydrogen atoms. For choosing the most suitable beam injector spin vector motion has been analytically studied in a linear accelerator and in a microtron. It is shown that the effect of electric and magnetic fields in a microtron upon polarization of accelerated beam is limited in the first approximation to a change of the precession frequency of the Psub(x) and Psub(y) polarization components. The Psub(z) component is stable in a microtron which renders it more suited to accelerating a cross-polarized than a linear accelerator. It is shown that when polarized particles are accelerated in a synchrotron, the magnetic field inhomogeneities and disturbances may affect the direction of the polarization vector. Ways are discussed of suppressing the particle depolarization effect by compensating for dangerous magnetic field disturbance harmonics
