In examination of the possibility of observing D‐D fusion reactions at or near room temperature, our group at Manitoba has searched for an enhancement in the neutron production rate resulting from stopping deuterons interacting with implanted deuterons in a metal matrix. This non‐equilibrium process was selected as an alternative to electrolysis as a means of injecting the material. The deuterons were implanted into the metal matrix by a small high current accelerator which accelerated a mixed beam of D+of energy 60 keV and molecular D2+which upon dissociation at the surface of the metal yields two 30 keV D+ions. The precise composition of the beam was unknown. The presence of neutrons was registered continuously during the experimental runs. Scintillation light was detected as the neutrons transferred a portion of their energy to protons in a large plastic scintillator detector. Anomalous occurrences were observed during the operation of the experiment, in the form of sudden increases in the observed neutron detection rates. We undertook to repeat the experiment under more controlled conditions, with the intent of resolving to our satisfaction whether anomalous neutron production was actually occurring. In addition, an attempt to measure X‐ray production within the target metal was made. The build up to deuterons in the metal matrix was such that where the density of deuterons in a commercially available TiD target would be expected to be on the order of 4×1028m−3, our implantation scheme resulted in deuteron densities up to 2×1031m−3in the matrix. We argue that the loss of deuterons from the matrix will be small compared to build up rates. The results of our 1989 experiment are being compared with theory and the results of a more recent one (July 1990), currently under analysis. Funding has recently been obtained from our local electric utility, Manitoba Hydro, for the production of analyzed beams of D0, D+and D2+for future implantation experiments. Work in this area is now under way.
