Description

A system for observation of X-ray synchrotron radiation (SR) beam position and its stabilization is described. The system consists of fluorescent screen using vacant part of SR beam at the user station. TV signal is processed by a computer. Codes developed determine the beam center of gravity. Digital feedback with control system provides correction of SR beam position at the user station. Digital feedback with control system provides correction of SR beam position at the user station. Uncertainty of vertical beam position is about 10 μm when measuring time is 10 s

Abstract (Russian)

Описана система наблюдения и стабилизации положения рентгеновского пучка синхротронного излучения (СИ) на экспериментальной станции пользователя. Система состоит из люминофора, регистрирующего неиспользуемую часть пучка СИ, и телекамеры. Разработанные программы обеспечивают обработку изображения пучка, определяя его центр тяжести. Цифровая обратная связь с системой управления обеспечивает коррекцию положения пучка СИ на станции. Получена неопределенность положения пучка СИ на люминофоре около 10 мкм при времени измерения около 10 с
