Observation of nuclear particles and their correlation with acoustic and electromagnetic emission from palladium targets loaded by deuterium AIP Conf. INTRODUCTION Our search for cold nuclear fusion in condensed matter began with elec-trolytic and deuterium-gas loading experiments at BYU in 1986. [1,2] In that year, we obtained evidence for neutron emissions, and we pursued our program of neutron detector development, which was hampered by low funding levels.[3] By December 1988, we had in hand a spectrometer to measure neutron energies [4]. We began applying the neutron spectrometer to search for neutron emissions during deuteron infusion into various metals and salts. In a few months of running, including light-hydrogen control studies and detector calibrations, we observed what we discerned (and still maintain [5]) to be significant neutron emission from partially-deuterided materials in non-static conditions and published our results (ref. 1). The rates observed were far too tiny to account for "excess heat" emissions in electrolytic cells reported about the same time [6] and unfortunately connected erroneously with our work. It is true that Van Siclen and Jones in an original paper on "piezonuclear fusion" written in 1985 [7] had discussed the possibility of "excess heat" (our 1985 terminology) in Jupiter due to d-d or p-d fusion in its metallic core, but this occurs on a far grander scale than achievable in the laboratory. The hypothesis of the occurrence of natural fusion [1,2,7] inside Jupiter or other planets remains an open and intriguing question (see papers by E. Paul Palmer and others in this Proceedings). In normal scientific fashion, we checked the results of ref. 1 by carrying out similar experiments with colleagues in Italy [8] and Los Alamos National Laboratory [9], with both experiments reporting anomalous neutron emissions from deuterium/metal systems under non-equilibrium conditions. The Los Alamos experiments showed a surprising aspect of these anomalous emissions, that is, bursts of hundreds of neutrons were detected in time windows of 128 #sec. (Our neutron spectrometer was too low in efficiency to delineate such bursts, but the detector developed by H. Menlove et al. [10] detected bursts clearly.) Random or uncorrelated neutron emissions were also reported at the 10a level. [9] We have since repeated our electrolysis experiments in different detectors with higher sensitivity and observed neutron yields up to …

Nuclear emissions during self-nucleated acoustic cavitation.
A unique, new stand-alone acoustic inertial confinement nuclear fusion test device was successfully tested. Experiments using four different liquid types were conducted in which bubbles were self-nucleated without the use of external neutrons. Four independent detection systems were used (i.e., a neutron track plastic detector to provide unambiguous visible records for fast neutrons, a detector...
متن کاملEstimation of gas emission released from a municipal solid waste landfill site through a modeling approach: A case study, Sanandaj, Iran
Sanitary landfill is the common strategy for municipal solid waste management in developing countries. Anaerobic decomposition of disposed wastes in landfill under favorable conditions will lead to the landfill gas (LFG) emissions, considering as emerging air pollutants. The emission of greenhouse gases, including methane, resulting from municipal solid waste disposal and treatment processes ar...
متن کاملAn apparatus to control and monitor the para-D2 concentration in a solid deuterium, superthermal source of ultra-cold neutrons
In a recent investigation of solid D2 as a UCN source[1], it was surmised that the yield of UCN is correlated with the spin states of the deuterium molecules. Subsequently, detailed neutron scattering calculations and measurements of the UCN lifetime in mixtures of paraand ortho-deuterium quantitatively verified this conjecture.[2,3,4,5,6] The work we report here was motivated by our attempt to...

Several experiments of loading Titanium samples with Deuterium from the gas phase, of changing the temperature of the samples over a wide range and of monitoring the neutron emission were done. Neutron emissions in very low intensity bursts, still significantly above the background were recorded, revealing that low energy nuclear reactions in condensed matter can be produced with a very low rat...
