Solar X-ray Monitor (XSM) is one of the scientific instruments onboard Chandrayaan-2 orbiter. The XSM along with instrument CLASS (Chandra’s Large Area soft X-ray Spectrometer) comprise the remote X-ray fluorescence spectroscopy experiment of Chandrayaan- 2 mission with an objective to determine the elemental composition of the lunar surface on a global scale. XSM instrument will measure the solar X-rays in the energy range of 1–15 keV using state-of-the-art silicon drift detector. The flight model of the XSM payload has been designed, realized and characterized for various operating parameters. XSM provides energy resolution of ~180 eV at 5.9 keV with high time cadence of one second. The X-ray spectra of the Sun observed with XSM will also contribute to the study of solar corona. The detailed description and the performance characteristics of the XSM instrument are presented in this article.Keywords

Chandrayaan-2 Large Area Soft X-ray Spectrometer (CLASS) is an X-ray fluorescence spectrometer experiment aimed at mapping the abundances of major rock-forming elements on the lunar surface. The instrument consists of swept charge devices with a passive collimator, visible light blocking filters and signal processing electronics designed and built at U.R. Rao Satellite Centre, Indian Space Research Organisation. CLASS will be the largest collecting area spectrometer flown to the Moon, and thus is expected to map the abundances of lunar elements with a higher sensitivity than ever at soft X-ray energies.Keywords
