摘要
We are presently building an array of angle integrating air Cherenkov counters for the study of VHE and UHE cosmic rays. The new array will be sensitive to extended air showers of energies > 5 x 10(13) eV and of zenith angles up to 35-degrees. The determination of the incident shower direction will be performed by fast timing measurements with an angular resolution of 0.5-5 mrad. The Cherenkov counters will allow us to obtain information on the shower energy and structure higher up in the atmosphere. The array will be combined with the existing HEGRA scintillation counter matrix on La Palma. The combination of the Cherenkov data and the data from the ground level scintillator matrix will provide a powerful tool for gamma/hadron discrimination. We expect to achieve hadron rejection ratios of > 10(3) when adding the proposed muon detectors, thereby making possible the detection of the diffuse gamma radiation presumed to be coming predominantly from the galactic plane.
