DEVICE TO DELIVER ULTRACOLD NEUTRONS ALONG FLEXIBLE NEUTRON GUIDES

摘要

FIELD: power engineering.;SUBSTANCE: device has a stationary vacuumised neutron guide made in the form of a stainless steep pipe, nickel or copper. The device is additionally equipped with a section of a neutron guide made as a flexible polyvinyl chloride tube, the inner wall of which has mirror surface. Values of average roughness of the inner wall of the flexible polyvinyl chloride tube do not exceed the length of the ultracold neutron wave length.;EFFECT: reduced losses of low energy neutrons during transportation, capability of delivering them into hard-to-access areas.;8 cl, 5 dwg, 1 tbl
