We present the RXTE high-energy X-ray spectrum of the supernova remnant SN 1006. The results of an analysis of the RXTE and ASCA data of this remnant support a previous report that the high-energy X-ray spectrum of the shell is dominated by synchrotron radiation from electrons that have been accelerated to energies as high as ~ 100 TeV. Furthermore, the results show that the non-thermal X-ray spectrum steepens with increasing energy as is expected for synchrotron emission. The recent detection of gamma rays at energies > 3 TeV from SN 1006 confirms that this remnant contains electrons that have been accelerated to very-high energies. While X-ray emission is observed from both the north-east and south-west rims of the remnant, no gamma-ray emission is observed from the south-west rim. We show that the RXTE X-ray data may or may not be consistent with the upper limit on the gamma-ray flux of the south-west rim. We review the radio through gamma-ray spectrum and discuss the implications of the data for Galactic cosmic-ray acceleration.
