Instrument details
Acronym HXI
Full name Hard X-ray Imager
Purpose To image solar flares in hard X-rays from ~30-200 keV.
Short description Has an angular resolution of 3.2 arc seconds, field of view of 40 arc minutes, and energy resolution (24% @ 32 keV). Adopts a similar principle used by the Hard X-ray Telescope (HXT) onboard the Japanese YOHKOH satellite using indirect imaging technique via spatial modulation.
