Solar X-Ray Monitor

XSM instrument provides the real time solar X-ray spectrum which is essential to interpret the quantitative elemental composition of the Moon from the orbiting satellite by the companion instrument Chandra's Large Area Soft x-ray Spectrometer (CLASS - developed at ISAC, Bangalore). X-ray fluorescence from the Moon is critically depend on the intensity of the Solar X-ray falling on the Moon. CLASS instrument will provide the global elemental composition of the Moon using the XSM data. XSM instrument will provide high cadence (spectrum for every second) data with high energy resolution. The flight model of XSM has been delivered to URSC on 6th December, 2017. XSM is working in the lunar orbit for more than 2 years providing many science results first of their kind.
