The emission characteristics of the electrodes metal hydride in gas discharge of low pressure

The ion-electronic (gamma) and electron-electronic (sigma) emission coefficients of metal hydride Zr50V50Hx and Ti50V50Hx accordingly were investigated. It is found that presence of the hydrogen in alloy brings about change values and behaviours gamma- and sigma-coefficients. The influence to density of the current of the beam ion on change the metal hydride gamma-coefficient was investigated. It is found that with increase the contents of the hydrogen in alloy the secondary ion-electronic emission coefficients for more thick beams of the primary particles was decrease. The investigations of hydrogen desorbsion from metal hydride electrodes Zr50V50Hx under influence of the particles of the plasma were studied. It is made suggestion that at interaction particles plasma with surface metal hydride electrode proceeds intensive hydrogen desorbsion from metal hydride.
