The remnant of SN 1006 AD was the first shell supernova remnant to show evidence of X-ray synchrotron emission, which may be detectable to photon energies of several tens of keV where it could be observed by the INTEGRAL satellite. However, nonthermal bremsstrahlung from the lowest-energy nonthermal electrons should also appear in this energy range. Observing emission due to either mechanism could put interesting constraints on the efficiency and maximum attainable energies of electron acceleration. We employ an imaging spectral code including calculations of emissivity due to both bremsstrahlung and synchrotron processes in order to predict images and spectra of SN 1006 as seen by INTEGRAL's IBIS and Jem-X instruments. We show that morphological and spectral differences should allow the two processes to be distinguished. We exhibit ranges of emission for models whose soft X-ray emission is consistent with Chandra and ASCA observations, and show how detected fluxes, or upper limits, from INTEGRAL can allow constraints on parameters such as magnetic-field strength and geometry, electron injection efficiency, and upstream density.
