【 摘 要 】

The behavior of small amounts of polarized {sup 3}He in a bath of superfluid {sup 4}He at temperatures below 1 K is critical to a new technique for measuring the EDM of the neutron. We report on studies to enhance the number of ultracold neutrons produced in such a bath, on the development of neutron tomography in gaseous mixtures, on magnet properties associated with the precession of {sup 3}He, and on preparations for tests of the distribution and diffusion coefficients of {sup 3}He in the bath.
