| Abstract(in English) | The improved Sc_20_3-dispersed-oxide-cathode with Tungsten-Film Coating has been developed. The capability of new cathode for high current density operation is as high as 1.5 times that of conventional Sc_20_3-dispersed-oxide-cathode. Ni and W interdiffuse and form a fine-grained and uneven Ni-W layer. This structure increases the opportunity for reaction. Sufficient free Ba is also formed within this structure. Ba_2Si0_4 (an insulator) is dispersed in the Ni-W layer. As a result, Si, Mg and W of the proper quantity in the Ni-W layer seem to contribute to free Ba production during long operation. |
