Abstract

The first imaging Cherenkov telescope of the HEGRA collaboration (CT1) detects VHE gamma rays in stand-alone mode. Last year CT1 was equipped with new high-reflectivity mirrors and a next-neighbor trigger which have enabled reduction of the energy threshold to around 700 GeV. In addition completely new software for the data acquisition has been developed and installed in the past months. Here we report on the features of the new system and some of the tests which have been performed with it. © 2000 American Institute of Physics. [ABSTRACT FROM AUTHOR]
