Abstract We propose a 900 ksec observation of the remnant of the supernova of 1006 AD, the Rosetta Stoneobject for the study of electron acceleration to very high energies. The combination of IBIS and Jem-Xspatial and spectral coverage should allow testing of the hyposthesis that the emission above 3 keVis dominantly synchrotron, and should either detect, or put limits on, a contribution from nonthermalbremsstrahlung. The angular diameter of SN 1006, 30, is large enough that IBIS will have sufficientspatial resolution to perform a simple discrimination on the highest-energy detectable hard X-rays:synchrotron emission should come from two opposing limbs, while bremsstrahlung should have amore uniform ring morphology. Jem-X will resolve SN 1006 with about 10 beams across its diameter,ample to search for a bremsstrahlung contribution and comparable to ASCA resolution at thermalX-ray energies. The energy range of 5 to 50 keV shows the lowest-energy suprathermal cosmic-rayelectrons, through bremsstrahlung, and the highest-energy electrons, through synchrotron radiation.Quantitative inferences from detections or limits can include the efficiency of shock acceleration ofelectrons, the maximum energies to which electrons can be accelerated, and indirect constraintson the mean remnant magnetic field strength. INTEGRAL can make a major contribution to theunderstanding of nonthermal emission from this important object, and through it, to the understandingof acceleration of particles at shocks anywhere in astrophysics.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
