The H.E.S.S. II Project (pdf)

The High Energy Stereoscopic System (H.E.S.S.) is an array of Imaging Atmospheric Cherenkov Telescopes for the detection of Very High Energy (VHE) gamma rays, i.e. those with an energy of the order TeV. It is operational since 2002 and consists of 4 telescopes of about 125 m^2 mirror area. To lower the energy threshold for gamma rays an additional telescope (H.E.S.S. II) is in preparation with a significantly increased mirror area of about 600 m^2 consisting of 851 individual hexagonal mirror facets. After an introduction into the H.E.S.S. II project different possible solutions for the construction of these mirror facets will be presented as well as a test setup for quality control.
