HESS-II performance in the low-energy domain
Y. Becherini1, A. Djannati-Atai1, M. Punch1

In mid-2009 a notable upgrade of the H.E.S.S. telescope system will take place: a new telescope with a 600 m^{2} mirror area and very-high-resolution camera (0.07°) will be positioned at the centre of the present configuration, with the aim of lowering the threshold and enhance its sensitivity in the 100 GeV to several TeV energy range. HESS-II will permit the investigation of the lower energy γ-ray spectra in various cosmic accelerators, giving information on the origin of the γ-rays observed, and will detect AGNs with a redshift greater than 0.2 (being less affected by absorption by Extragalactic Background Light - EBL - in this energy range) and will search for new classes of very high energy γ-ray emitters (pulsars, microquasars, GRB, and dark matter candidates).
