  • Water bath calorimetric study of Excess Heat Generation in 'resonant transfer' plasmas
    Journal of Applied Physics, 2004
    Co-Authors: Jonathan Phillips, Randell L. Mills, X. Chen
    Abstract:

    Water bath calorimetry was used to demonstrate one more peculiar phenomenon associated with a certain class of mixed gas plasmas termed resonant transfer, or RT plasmas. Specifically, He/H2 (10%) (500 mTorr), Ar/H2 (10%) (500 mTorr), and H2O(g) (500 and 200 mTorr) plasmas generated with an Evenson microwave cavity consistently yielded on the order of 50% more Heat than non RT plasma (controls) such as He, Kr, Kr/H2 (10%), under identical conditions of gas flow, pressure, and microwave operating conditions. The Excess power density of RT plasmas was of the order 10 W / cm-3. In earlier studies with these same RT plasmas it was demonstrated that other unusual features were present including dramatic broadening of the hydrogen Balmer series lines, unique vacuum ultraviolet (VUV) lines, and in the case of water plasmas, population inversion of the hydrogen excited states. Both the current results and the earlier results are completely consistent with the existence of a hitherto unknown exothermic chemical reaction, such as that predicted by Mills, occurring in RT plasmas.

    Abstract:

    Water bath calorimetry was used to demonstrate one more peculiar phenomenon associated with a certain class of mixed gas plasmas, termed resonant transfer (RT) plasmas. Specifically, He∕H2(10%) (500mTorr), Ar∕H2(10%) (500mTorr), and H2O(g) (500 and 200mTorr) plasmas generated with an Evenson microwave cavity consistently yielded on the order of 50% more Heat than non-RT plasma (controls) such as He, Kr, Kr∕H2(10%) under identical conditions of gas flow, pressure, and microwave operating conditions. The Excess power density of RT plasmas was of the order 10Wcm−3. In earlier studies with these same RT plasmas it was demonstrated that other unusual features were present including dramatic broadening of the hydrogen Balmer series lines, unique vacuum ultraviolet lines, and, in the case of water plasmas, population inversion of the hydrogen excited states.

  • Upconversion studies of flashlamp-pumped Cr,Tm,Ho:YAG
    Advanced Solid State Lasers, 1991
    Co-Authors: S. R. Bowman, M. J. Winings, R. C. Y. Auyeung, J. E. Tucker, S. K. Searles, Barry J. Feldman
    Abstract:

    We report measurements on flashlamp pumped YAG crystals doped with chromium, thulium and holmium. Near room temperature laser operation on the 2.1 μm holmium transitions was characterized using a frequency selective resonator. Small signal gain and stored energy lifetimes were analyzed to determine the strength and dependence of loss mechanisms. Analysis of thermal lensing experiments demonstrated a high degree of Excess Heat Generation in this material.

  • Laser and spectral properties of Cr, Tm, Ho:YAG at 2.1 mu m
    IEEE Journal of Quantum Electronics, 1991
    Co-Authors: S. R. Bowman, M. J. Winings, R. C. Y. Auyeung, J. E. Tucker, S. K. Searles, Barry J. Feldman
    Abstract:

    The authors study the loss process in a uniformly pumped amplifier experiment. The impact of the loss mechanism on laser performance is discussed and its dependence on excited state density is considered. An extensive set of measurements was performed on flashlamp pumped YAG crystals doped with chromium, thulium, and holmium. Near-room-temperature laser operation on the 2.1 mu m holmium transitions was characterized using a frequency selective resonator. Small signal gain and stored energy lifetimes were analyzed to determine the strength and dependence of loss mechanisms. The analysis of the thermal lensing experiments demonstrated a high degree of Excess Heat Generation in this material. >
