[en] We have produced long lifetime ³He spin-exchange cells from Corning 7056 glass. The lifetimes of single cells have approached the ³He-³He bulk-limited lifetime (250 h at a density of 8 x 10¹⁹ cm^-3, (3 amagats)). Corning 7056 glass has the advantage of being a much easier glass for the glassblower to work, allowing for more complex cell designs. In our experiments at Michigan and at SLAC, we have implemented laser diode arrays for spin-exchange optical pumping. In particular, for experiment E154 at SLAC, we achieved high polarizations in high-density ³He targets using laser diode arrays. (orig.)
