We report on a survey of the inner part of the Galactic Plane in very highenergy gamma-rays, with the H.E.S.S. Cherenkov telescope system. The GalacticPlane between +-30deg in longitude and +-3deg in latitude relative to theGalactic Centre was observed in 500 pointings for a total of 230 hours,reaching an average flux sensitivity of 2% of the Crab Nebula at energies above200 GeV. Fourteen previously unknown sources were detected at a significancelevel greater than 4 sigma after accounting for all trials involved in thesearch. Initial results on the eight most significant of these sources werealready reported elsewhere. Here we present detailed spectral and morphologicalinformation for all the new sources, along with a discussion on possiblecounterparts in other wavelength bands. The distribution in Galactic latitudeof the detected sources appears to be consistent with a scale height in theGalactic disk for the parent population smaller than 100 pc, consistent withexpectations for supernova remnants and/or pulsar wind nebulae.Comment: Accepted for publication in Ap
