Replika Mirrors - Nearly Loss-Free Guides For Ultracold Neutrons
نویسنده
چکیده
The reflectivity of ultracold neutron (UCN) guides produced with a dedicated technique called Replika has been studied. The guides are made of nickel, where the surface quality was copied from a glass layer. This results in a surface roughness smaller than 10 Å. The reflectivity was measured to be 99.9 % or higher. Those guides can be used at present or future UCN sources to transport UCN over long distances to the respective experiments without significant losses.

Comment on “A proposed method for measuring the electric dipole moment of the neutron using acceleration in an electric field gradient and ultracold neutron interferometry ”, II
We discuss the proposal of Freedman, Ringo and Dombeck [1] to search for the neutron electric dipole moment by use of the acceleration of ultracold neutrons in an inhomogeneous electric field followed by amplification of the resulting displacement by several methods involving spin independent interactions (gravity) or reflection from curved (spin independent) mirrors. We show that the proposed ...

متن کاملThe Slab Waveguide 6.1 Guided Waves in a Metal Guide
It is now time to consider more effective guiding structures for electromagnetic waves. To introduce the basic ideas, we shall start with a very simple geometry, the metal-walled guide. Though this is not actually used at optical frequencies, it contains nearly all the features of more useful guides and can be analysed with little mathematics. The metalwalled guide consists of two plane mirrors...
متن کاملMeasurement of the trapping lifetime close to a cold metallic surface on a cryogenic atom-chip
We have measured the trapping lifetime of magnetically trapped atoms in a cryogenic atom-chip experiment. An ultracold atomic cloud is kept at a fixed distance from a thin gold layer deposited on top of a superconducting trapping wire. The lifetime is studied as a function of the distances to the surface and to the wire. Different regimes are observed, where loss rate is determined either by th...
متن کاملCalculation of the Ultracold Neutron Upscattering Loss Probability in Fluid Walled Storage Bottles using Experimental Measurements of the Liquid Thermomechanical Properties of Fomblin
We present experimental measurements of the properties of a liquid “Fomblin” surface obtained by the quasielastic scattering of laser light. The properties include the surface tension and viscosity as functions of temperature. The results are compared to measurements of the bulk fluid properties. We then calculate the upscattering rate of ultracold neutrons (UCN) from thermally excited surface ...
