  Dielectrons play an important role in heavy ion collisions since they are
produced during all stages of the collision and interact only
electromagnetically. The PHENIX experiment was upgraded with the Hadron Blind
Detector which provides excellent background rejection by removing pairs from
both partially reconstructed Dalitz decays and photon conversions. In these
proceedings we will report on the results obtained from 2009 data in p+p
collisions using the HBD as well as the Au+Au results obtained in 2010.
