HESSJ0835{455 is the TeV counterpart of the Pulsar Wind Nebula Vela X rst detected with aradiotelescope. IthasbeenobservedwiththeHighEnergyStereoscopicSystem(H.E.S.S.)from2003to2009. H.E.S.S.isanarrayoffourImagingAtmosphericCherenkovTelescopes,such instruments detecting the Cherenkov light which is generated in air showers inducedby -ray photons. The Cherenkov telescope technique exhibits a high background levelintroduced by the air showers of charged cosmic rays. Detailed studies of the propertiesof the H.E.S.S. background will be presented.
