Аннотация

Рассмотрен еще один подход при моделировании корпускулярно-оптических систем для анализа потоков заряженных частиц. Обязательным для всех рассмотренных и использованных ранее методов было выполнение условия пространственной фокусировки пучка частиц. Однако это строгое условие не всегда выполнимо в сочетании с другими требованиями. При использовании в качестве основного элемента цилиндрического электростатического зеркального анализатора пространственная фокусировка пучка несовместима с фокусировкой во времени пролета по энергии. В работе рассмотрена возможность использовать режим коллимирования пучка заряженных частиц, тем самым исключив необходимость выполнения условия фокусировки.
