The remnants of these supernovae are believed to be sourcesof the Galactic cosmic rays (CRs). However, it is still an open question whichprocessestakeplaceintheproductionofCRs. TheCRsitselfarriveisotropicallyon Earth, as they get deflected by interstellar magnetic fields. To study theacceleration regions of CRs, gamma rays which are produced in the vicinityof these regions are observed. In the very-high-energy waveband these gammarays are detected with Imaging Atmospheric Cherenkov Telescopes making useof the atmosphere as a part of the detector. To date the H.E.S.S. experimentis the most sensitive telescope array in this field. In this work the analysisof H.E.S.S. data from three supernova remnants is presented and it is shownthat two of them emit very-high-energy gamma rays.
