Description
A background-free measurement of neutrinoless double beta decay can be achieved
with the detection of the daughter nucleus. Methods to image the daughter
barium ion in the decay of xenon-136 are being developed for use in high
pressure gas time projection chambers by the NEXT collaboration. A major
remaining challenge is the transport of the barium ion to a small imaging
region within the detector. In this talk I will discuss the plans for testing
RF carpet performance in high pressure gas, early simulation results, and
experimental tests of RF high voltage behavior in high pressure systems. I will
also discuss our studies of ion drift properties in DC fields in high pressure
gases.
