Abstract:
We report the measurements of depolarization probabilities of polarized H3 e in a rectangular acrylic cell with a deuterated tetraphenyl butadiene-doped deuterated polystyrene coating filled with superfluid H4 e at ∼330mK with a magnetic holding field of ∼7.3G. We achieve a wall depolarization probability of ∼1.0× 10-7. Such a surface will find application in a new experiment searching for the neutron electric dipole moment and other applications. © 2009 The American Physical Society.
