Abstract
The paper is devoted to the discussion of the possibility of creating UCN sources based on the principle of pulsed accumulation (PA) in traps. The implementation of the PA principle would make it possible to create a source with a flux of UCN in a trap significantly exceeding the time average. The paper provides a comparative analysis of various approaches to the implementation of the idea of PA of UCN in traps remoted from the place of their generation. Based on this analysis, the concept of the UCN source, the creation of which is planned at the IBR-2M pulse reactor, was formulated. A distinctive feature of the designed source is a combination of several approaches to ensuring the pulsed structure of neutron bunches reaching the UCN trap. One of them is the deceleration of the pulsed flux of VCN using a resonant flipper, the second is the use of compensating time lenses.
期刊介绍:
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
