It is shown that the measured primary and secondary CR nuclei energy spectra as well as the observed positron-to-electron ratio are consistent with the origin of GCRs up to the energy 10^17 eV in SNRs. Existing SNR emission data provide evidences for efficient CR production in SNRs accompanied by significant magnetic field amplification. In some cases the nature of the detected gamma-ray emission is difficult to determine because key SNR parameters are not known or poorly constrained.", "revisions": [ { "version": "v1", "updated": "2014-12-25T07:07:46.000Z" } ], "analyses": { "keywords": [ "galactic cosmic ray", "supernova remnants", "secondary cr nuclei energy spectra", "significant magnetic field amplification", "existing snr emission data" ], "tags": [ "conference paper", "journal article" ], "publication": { "journal": "Nuclear Physics B Proceedings Supplements", "year": 2014, "month": "Nov", "volume": 256, "pages": 23 }, "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1335612, "adsabs": "2014NuPhS.256...23B" } } }
