The ratio of atomic line intensities from species of the same charge state are functions of Te and ne.  Experiments were performed last December with the aim of utilizing this relationship to measure Te and ne in over the divertor in 2D space on TCV.  Seven Helium lines were imaged simultaneously in the divertor with the new MANTIS diagnostic. This experiment and preliminary data analysis will be discussed at this talk.
