DESCRIPTION:Speakers: Yasunobu Uchiyama (Rikkyo University)\nDiffusive sho
 ck acceleration (DSA)\, a well-developed theory of the acceleration proces
 s at work in supernova remnants (SNRs)\, lays the foundation for the SNR p
 aradigm of the CR origin\,  though key problems are yet to be solved. Dete
 rmining the acceleration efficiency is one of the key issues\, where the t
 erm “acceleration efficiency” carries two different meanings\; one is 
 related to the maximum attainable energy\, and the other is the energy con
 tent of CRs. Synchrotron X-ray emission produced by highest energy electro
 ns with energies of tens of TeV\, and gamma-ray emissions either by relati
 vistic electrons via IC scattering or by high-energy protons via pion-deca
 y can provide information about the acceleration efficiencies at SNR shock
 s. We will report on our recent work on X-ray and GeV gamma-ray observatio
 ns of some supernova remnants. Also we will discuss prospect for the upcom
 ing X-ray observatory\, ASTRO-H\, which allows us to perform X-ray spectro
 scopy of extended objects with unprecedented spectral resolution (7 eV).\n
