Аннотация
Рассмотрена возможность использования синхротрона формы-8 в качестве замены Нуклотрона для ускорения поляризованных протонов и дейтронов в комплексе коллайдера NICA. Арки синхротрона размещены внутри туннеля коллайдера NICA. Представленный инжектор позволяет сохранять поляризацию и осуществлять инжекцию любого сорта частиц (p, d, ³He и др.) в коллайдерные кольца во всем диапазоне энергий. Благодаря своей форме кольцо работает в режиме спиновой прозрачности. Управление направлением поляризации осуществляется с помощью спинового навигатора, использующего слабые соленоидальные поля. Синхротрон также может использоваться в качестве накопительного кольца для высокоточных экспериментов с поляризованными пучками помимо применения в качестве инжектора для коллайдера. В работе приводятся результаты численного моделирования спиновой динамики при ускорении протонов и дейтронов.
