The Process of Cataphoresis to Obtain a High Purity Xe gas to Detect Zero Nuetrino Double-Beta Decay
Abstract
Zero neutrino double beta decay is of significant importance to the scientific community. In order to detect zero neutrino double beta decay, extremely pure Xe gas, with almost no atoms of radon, is needed. Discussed here is the possibility of utilizing cataphoresis on a continuous flow of the rare gas admixture to purify xenon in the recirculation system of a large (200kg) xenon zero neutrino double beta decay experiment. Steady state cataphoresis has been utilized to separate rare gases by using the electric field of the positive column of the glow discharge. But a useful flowing system has not been investigated previously. Design considerations and construction of a continuous flow setup for cataphoetric segregation of Helium gas with an Ar impurity will be described. Preliminary results will be reported. The possibility of performing the same process with Xe gas containing a very small amount of Radon impurity will also be considered.
