Спутник ФКИ. HXMT. [Редактировать]

Hard X-ray Modulation Telescope (HXMT) — орбитальная китайская рентгеновская космическая обсерватория для наблюдения чёрных дыр, нейтронных звезд и других явлений в рентгеновском и гамма-диапазонах космического излучения, запуск которой запланирован на 2017 год. Он создан на основе платформы, на базе которой создан исследовательский спутник наблюдений JianBing 3. Проект разрабатывается с 2000 года Министерством науки и технологий Китая, совместно с китайской Академии наук и в Университетом Цинхуа. Предполагается, что в ходе проведения наблюдений аппарат обнаружит примерно 1000 новых источников, включая активные галактические ядра, квазары и объекты галактического фона, а затем будет выполнять детальное исследование отдельных объектов, в числе которых черные дыры и нейтронные звезды. HXMT также будет осуществлять мониторинг иных космических источников и проводить периодический обзор галактической плоскости.
На борту аппарата установлены три основные полезные нагрузки:

  • Ренгеновский телескоп (20-250 кэв, 5100 см²) 
  • Ренгеновский телескоп (5-30 кэв, 952 см²)
  • Ренгеновский телескоп (1-15 кэв, 384 см²) 

Все эти три инструмента используют метод прямой демодуляции и сканирования.
