| 内容記述 | We propose to experimentally verify a principle of a substantially new type of compact source for Ultra Cold Neutrons (UCN) in support of designing a practical source dedicated to researches on fundamental particle physics in the 21^<st> century such as the electro-weak interaction, the new models beyond the standard model, the gravity, and so on with improved sensitivity. The novelty of this UCN source is to efficiently accumulate UCN emitted in a pulsed scheme from a surface of a superthermal converter, solid deuterium (SD_2) by using a large kick-out velocity (～5 m/s) of UCN from the SD_2 surface and a moving membrane synchronized with pulsed proton beam. This will enable us to make a much more compact UCN source with a performance higher than others ever constructed. We perform experimental verification of the proposed concept by making use of a prototype assembly consisting of the SD_2 converter, a moving membrane, a compact UCN storage vessel and a UCN detector with pulsed proton beam. As a promising pre-moderator, solid mesitylene (C_6H_3(CH_3)_3) operated at low temperatures (≦ 20 K) is examined on the suitability for a pre-moderator satisfying a time structure condition required for the present method of synchronized UCN storage. This test will be done by observing the time dependence of the intensity and the energy spectra of cold neutrons from solid mesitylene with the TOF method. For this purpose, we will observe the time dependences of energy spectra for produced cold neutrons emerging out of the mesitylene pre-moderator by a TOF method. | |||||||||||
