Accumulator of cold and very cold neutrons

Publications, 23 August 2023

We offer to your attention a preprint “Accumulator of cold and very cold neutrons” P13-2023-28 issued by the JINR Publishing Department. The author is Yuri Nikitenko.

A circle mirror accumulator of cold and very cold neutrons for neutron source is proposed. The relations are obtained for calculating of accumulator parameters, neutron current density, and hold time. It is shown the gain factors for current density and hold time can achieve a hundred. Some possibilities of creating and using an accumulator in physical investigations are considered.

The study has been carried out in the Frank Laboratory of Neutron Physics at JINR.
