Query: The Ion Fluorescence Chamber (IFC): A new concept for directional dark
  matter and topologically imaging neutrinoless double beta decay searches   We introduce a novel particle detection concept for large-volume, fine
granularity particle detection: The Ion Fluorescence Chamber (IFC). In
electronegative gases such as SF$_6$ and SeF$_6$, ionizing particles create
ensembles of positive and negative ions. In the IFC, positive ions are drifted
to a chemically active cathode where they react with a custom organic turn-on
fluorescent monolayer encoding a long-lived 2D image. The negative ions are
sensed electrically with course resolution at the anode, inducing an optical
microscope to travel to and scan the corresponding cathode location for the
fluorescent image. This concept builds on technologies developed for barium
tagging in neutrinoless double beta decay, combining the ultra-fine imaging
capabilities of an emulsion detector with the monolithic sensing of a time
projection chamber. The result is a high precision imaging detector over
arbitrarily large volumes without the challenges of ballooning channel count or
system complexity. After outlining the concept, we discuss R\&D to be
undertaken to demonstrate it, and explore application to both directional dark
matter searches in SF$_6$ and searches for neutrinoless double beta decay in
large $^{82}$SeF$_6$ chambers.
