Release of Hydrogen Isotopes from Pd under Radiation, Joule, and Thermal Exposure

Research output: Contribution to journalArticlepeer-review

Abstract

Abstract: The release of hydrogen isotopes (H, D) from Pd is studied under linear heating (a) by an accelerated electron beam, (b) by alternating current Joule heat (50 Hz) passed through the samples, and in external coaxial furnaces in (c) metallic (stainless steel) and (d) quartz vacuum cells. The cathode saturation of Pd samples with hydrogen and deuterium is used. The studies are performed in a high-vacuum installation. The recording of gases leaving the materials is carried out by mass spectrometry. The maximum shift in the position of the temperature maxima of the thermal-gas release of hydrogen and deuterium from palladium to the low-temperature region is observed when the samples are heated by electric current and heated in the quartz vacuum cell. The mechanisms of the release of hydrogen isotopes from metals due to the accumulation of electron-beam energy and electromagnetic field by the hydrogen subsystem of the crystals are considered.
