Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The paper presents the results of the investigation of a neutral-hydrogen pulse injector based on Penning discharge with a metal hydride hollow cathode. The source of chemically pure hydrogen is a getter alloy Zr₅₀V₅₀ made
in the form of a hollow cathode. The main release of hydrogen into the gas phase occurs under the influence of discharge current (about 20 A) in a short period of time (several hundred microseconds), during the operation in the
high-current discharge regime. It is shown, that the propagation velocity of the gas front depends on the discharge
current and is determined by the hydrogen temperature. The maximum velocity of gas front propagation is obtained
at the level of 5·10⁵
cm/s. The amount of hydrogen desorbed per 400-μc pulse isabout 1.5·10⁻³
cm³ under normal
conditions and the energy is expended on the level of 0.34 J. |
