Instrument details
Acronym IXAE
Full name Indian X-ray Astronomy Experiment
Purpose To study periodic and aperiodic intensity and spectral variations in X-ray sources (Sun and bright stars)
Short description Assemblage of three co-aligned collimated Pointed Proportional Counters (PPC) operating in the energy range 2-20 keV; and a X-ray Sky Monitor (XSM), energy range 2-8 keV
Background New development
