SN 1006: A Laboratory for Cosmic Ray Acceleration

We propose to observe SN 1006 with the RGS as prime instrument using twopointings of each 50virgulks. We will use spectroscopic diagnostics to investigatethe various shock fronts around the remnant, of which the cosmic rayacceleration region on the NE limb should be particularly interesting. Electrontemperature diagnostics in Helike systems N VI and O VII (and higher, Ne IX,Mg XI if possible) will be used to search for electrons energized at the NE limbto form the population of seed particles for cosmic ray acceleration. RGSspectra will be combined with EPIC images to account as fully as possible forthe effect of the spatial extent of the source on the spectral resolution.Additionally we will use the OM to search for synchrotron radiation in theopt/UV truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
