| contents | The synthesis and application of deuterated polystyrene (dps) films is discussed. Ultracold neutron storage properties and the Fermi potential of dps films is measured with the result that Tstore=700 +/- 200 sec for dps in the bottle used and the Fermi potential is about 165neV. The behavior under application of high electric fields in vacuum is measured; the films are sufficiently stable to use in a neutron EDM bottle. Also, the relaxation rate of nuclear spin polarized 199Hg on dps films is measured giving a wall lifetime of 20 sec/cm mean free path, which should make the development of an Hg volume magnetometer possible. |
