Instrument details
Acronym RGS
Full name Reflection Grating Spectrometer
Purpose X-ray measurement in the Interplanetary space
Short description Array of reflection gratings placed in the converging beam of an XMM-Newton telescope mirror module, exploiting two out of the three mirror modules. X-ray measured spectrum range 0.33-2.5 keV with resolving power E/ΔE ranging from 150 to 800.
Background RGS is complementary to the other two XMM-Newton instruments: the European Photon Imaging Camera (EPIC), that measures X-rays with higher spatial resolution and lower spectral resolution than RGS; and the Optical Monitor (OM), that provides complementary information on UV and VIS
Scanning Technique CCD viewing the interplanetary space in a 30 arcmin FOV addressing changing sectors as the satellite moves in the 40° inclination HEO.
Resolution 6 arcsec
Coverage / Cycle Large fraction of the interplanetary space each orbital period (48 h). Typical sampling interval presumably around 60 s
Mass Power Data Rate
