Зарядталған бөлшектердің ағындарын талдау үшін корпускулалы-оптикалық жүйелерді модельдеудің жаңа тәсілі қарастырылған. Бұрын қарастырылған және қолданылған барлық әдістер үшін бөлшектер шоғын кеңістіктік тоғыстау шарты міндетті болды. Алайда, бұл қатаң шарт басқа талаптармен бірге әрдайым орындала бермейді. Негізгі элемент ретінде цилиндрлік электрстатикалық айналы талдағыштың қолданған кезде, шоқтың кеңістіктік тоғысталуы энергия бойынша ұшу уақытында тоғыстаумен үйлеспейді. Жұмыста зарядталған бөлшектердің шоғын коллимирлеу режимін қолдану мүмкіндігі қарастырылған, осылайша тоғыстау шартын орындау қажеттілігін жояды.
