Study On Abnormal Excess Heat In Palladium Deuterides Triggered By A Yag Frequency Doubling Laser

In this paper, A beam of YAG double frequency laser was used (wavelength=532nm) to trigger a certain volume of palladium lattice and induced a low energy nuclear reaction between d-d atoms in this D/Pd gas loading system. About400joules excess heat energy was produced within one hour, which was corresponded to1.6×103eV energy for each palladium atom. This result showed that the exothermic order of low-energy nuclear reaction was higher than the chemical exothermic order, and lower than the order of traditional thermonuclear fusion reaction, and this phenomenon could be a new physical process.The author verified the hypothesis of the optimal matching conditions of the abnormal exothermic experiment in the low energy condition through the laser-triggering experiments of40,60,80and100mJ while the deuterium loading ratio was0.099. The abnormal exothermic experiment was successfully repeated when the loading ratio is about0.1and the input power of laser is400mW. The excess heat power obtained was much higher than the power, about ten times, some people got before.The author found out a new triggering condition for excess heat when the input power of laser was1000mW, there was a small excess heat in this condition.In addition, the author made an improvement on the experiment system. The old vertical rubber plug sealing glass structure system was changed into the horizontal guard staple flange stainless steel reaction chamber. The charge-deuterium intake valve changed into a needle valve. Make the deuterium intake rate became controlled precisely. Finish the determination of the system constant k for the new experiment device. Optimize the thermal treatment process for palladium material. Summarize and revised the processed conditions of the experiments in deuterium loading、 annealing and surface activation.
