Hard X-ray Modulation Telescope (HXMT) also known as Insight (Chinese: 慧眼)[3] is a Chinese X-ray space observatory, launched on June 15, 2017[2] to observe black holes, neutron stars, active galactic nuclei and other phenomena based on their X-ray and gamma-ray emissions.[4] It is based on the JianBing 3 imagery reconnaissance satellite series platform.

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.

Payload

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.[5] 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",[6] which has shown promise in de-convolving the raw data into images while preserving excellent angular and energy resolution.

The satellite has three payloads, the high energy X-ray Telescope (20–250 keV), the medium energy X-ray telescope (5–30 keV), and the low energy X-ray telescope (1–15 keV)[2]
