Abstract

A prototype gravity analyzer using UCN has been constructed in KUR. The principle of the scattered energy analysis is 'fall-focusing'. The scattering angle is divided into five sections to analyze the momentum transfer. The second and fourth regions of five divisions are already installed in this analyzer. The gravity analyzer using UCN has a high resolution for both energy and momentum. The present device has a high geometrical efficiency because reflection mirrors with wide solid angles are provided to collect scattered neutrons.
