Hard X-ray Modulation Telescope

Hard X-ray Modulation Telescope

Hard X-ray Modulation Telescope (HXMT) is a planned X-ray space observatory from China. The spacecraft is planned for launch between 2014 and 2016.[1] It will be China's first astronomy satellite.[2] It is based on the JianBing 3 imagery reconnaissance satellite series platform.

The main scientific instrument is an array of 18 NaI(Tl)/CsI(na) slat-collimated "phoswich" scintillation detectors, collimated to 5.7°×1° overlapping fields of view.[3] The main NaI detectors have an area of 286 cm2 each, and cover the 20—200 keV energy range. Data analysis is planned to be by a direct algebraic method, "direct demodulation",[4] which has shown promise in de-convolving the raw data into images while preserving excellent angular and energy resolution.

The project, a joint collaboration of the Ministry of Science and Technology of China, the Chinese Academy of Sciences, and Tsinghua University, has been under development since 2000.
