Abstract
The results of measurements of the efficiency of a 6LiD thermal-to-fast neutron converter for neutrons from DT and 6LiT fusion reactions with energy 14 MeV in the experimental channel of an IVV-2M reactor are presented. The first experimental estimates of the conversion coefficients for the corresponding fusion reactions are obtained: K D ≅ 2.11·10–4 and K Li ≅ 1.36·10–4. The value found in this work for the total conversion coefficient ≅3.47·10–4 is approximately 1.7 times greater than the previously measured value and about 20% greater than the maximum computed estimate for a 6LiD converter.
An experimental apparatus with a 6LiD converter in an IVV-2M channel is an accessible, comparatively inexpensive, and unique (for now) source of 14 MeV neutrons that can provide continuous and approximately uniform irradiation of ∼Ø4 × 20 cm samples by neutrons from DT and 6LiT fusion ≅2.7·1010 sec–1·cm–2 for a comparatively long time (∼500 h).
