    "abstract": "A new Hadron Blind Detector (HBD) for electron identification in high density\nhadron environment has been installed in the PHENIX detector at RHIC in the\nfall of 2006. The HBD will identify low momentum electron-positron pairs to\nreduce the combinatorial background in the $e^{+}e^{-}$ mass spectrum, mainly\nin the low-mass region below 1 GeV/c$^{2}$. The HBD is a windowless\nproximity-focusing Cherenkov detector with a radiator length of 50 cm, a CsI\nphotocathode and three layers of Gas Electron Multipliers (GEM). The HBD uses\npure CF$_{4}$ as a radiator and a detector gas. Construction details and the\nexpected performance of the detector are described.",
