THERMAL NEUTRON CROSS SECTIONS OF COLD-MODERATORS

摘要：

This paper reviews some moderators for cold neutron source. As a good cold moderator, solid methane was studied and evaluated using the new synthetic frequency spectrum theory(SFS). Due to its high proton density and easy handling, mesitylene (not included in ENDF/B) has also been considered as a very good moderator for cold neutron source. Evaluation of this material in different crystalline phases was done by using a preliminary frequency spectra built combining experimental and synthetic contributions. As a result, we have generated ACE format scattering data files by the NJOY code, with validations of comparing total cross sections from experiments.
