Проблема максимального времени когерентности прецессии спина частиц в сгустке сводится к минимизации разброса длин орбит всех частиц. Это достигается введением секступолей с полями, которые минимизируют хроматичность частоты прецессии спина. Мы экспериментально обнаружили, что минимизация хроматичности бетатронного движения приводит к минимизации хроматичности частоты прецессии спина. В этой статье мы исследуем эту взаимосвязь.</p></abstract><trans-abstract xml:lang="en"><p>   One possible method of measuring the electric dipole moment of an elementary particle consists in measuring the average spin precession frequency of a polarized beam. The problem of maximizing the spin coherence time of a bunched beam is reduced to the minimization of the particles’ orbit length dispersion. This is achieved by introducing sextupoles with fields minimizing the chromaticity of the spin frequency. We have found experimentally that minimizing the chromaticity of betatron motion leads to the minimization of the chromaticity of the spin frequency. In this paper we explore this relationship.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>удлинение орбиты</kwd><kwd>бетатронные колебания</kwd><kwd>хроматичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>orbit lengthening</kwd><kwd>spin</kwd><kwd>betatron oscillation</kwd><kwd>chromaticity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wilson E.J.N. // Report CERN 95-06. 1995.
