Description
We report the results of studies showing that temperature dependent photo-luminescence is the likely source of unexpected large background rates in afterglow searches for dark sector phenomena. Using this information, we examine the possibility of a room temperature afterglow search that automatically eliminates this background. Finally,
without this background, we discuss a modest search effort that would explore the chameleon afterglow half-life range: 0.1 ≤ T1/2 ≤ 200 second, corresponding to the photon coupling constant range: ~3×10^13 ≤ βγ ≤ ~3×10^14.
