Experimental results on measurement of dd-reaction
cross sections in the energy range of 0.1–1.5 keV
using the Z-pinch technique are presented. The
experiment was fulfilled at the high current generator
of the High-Current Electronics Institute, city of Tomsk,
Russia. The dd-fusion neutrons were registered by
time-of-flight scintillator detectors and BF3
detectors of thermal neutrons. The estimates were obtained at 90%
of the confidence level for the upper limits of the neutron-producing
dd-reaction cross sections for average deuteron collision
energies of 0.11, 0.34, 0.37, and 1.46 keV. These results substantiate
feasibility to get a cross section magnitude for dd-reaction
in the range of the collision energy of 0.8–3 keV using similar
technology at the pulse current level of 2–3 MA.
