The Medium Energy (ME) X-ray telescope onboard the Insight-HXMT astronomy satellite

Understand

The Medium Energy X-ray telescope (ME) is one of the three main telescopes on board the Insight Hard X-ray Modulation Telescope (Insight-HXMT) astronomy satellite.

• ME contains 1728 pixels of Si-PIN detectors sensitive in 5-30 keV with a total geometrical area of 952 cm2.
• Application Specific Integrated Circuit (ASIC) chips, VA32TA6, is used to achieve low power consumption and low readout noise.
• The collimators define three kinds of field of views (FOVs) for the telescope, 1{\deg}{\times}4{\deg}, 4{\deg}{\times}4{\deg}, and blocked ones.
