Paper Abstract

Very cold neutrons (VCN) with the velocity below about 40 m/s can be confined in a guide tube torus with the tube diameter of about 5 cm and curved with a radius of about 4 meters. Thus, arranging a number of magnetic devices along the torus which force adiabatic spin flips of VCN in the strong magnetic field, a magnetic pumping of VCN into a defined energy band can be attained and a high density of ultracold neutrons will be produced with feeding VCN continuously from a connected guide tube. An analytical work on the proposed system with the realistic design parameters under actual VCN feeding intensity from the KUR VCN facility will be reported. The preparation of an experimental device is also under progress according to the present analysis in order to test the working principle of the proposed magnetic pumping of VCN to ultracold neutrons.
