We have not quite identified exactly what was causing the previous targets to have poor lifetimes, but we have developed a method that, seemed to produce cells wit Studies of Polarized Helium-3 Cell Lifetimesh longer lifetimes. The testing of these processes is not complete, but getting a couple of improved cells Is very promising.2Introduction2.1PolarizatStudies of Polarized Helium-3 Cell Lifetimes
