The high friction coefficients between the inner Mo electrode and the cathodes Al electrodes in large-area, high-power devices causes Al to stick to Mo or causes short circuiting due to the large elongation of the Al electrodes. Equipment which can reproduce these friction behaviors has developed. The friction coefficients and the Al elongation were evaluated for various combination systems. It was found that friction coefficients and Al elongation were much smaller for Mo/Cd||Al and Mo||Mo foil||Al systems than those for the conventional Mo||Al system. The reliability of large-area, high power devices using Mo foil was satisfactory.
