要約(日本語): In order to clarify the instability phenomena of a low current in the vacuum, the optical characteristics of a low current vacuum arc was investigated by using Cu, CuW, CuCr, CuBi, and AgWC electrodes. We measured the spectrum-line intensity distribution against wavelength during arc discharge for each electrode. For each component of every electrode material, the intensity and its attenuation speed of the metal vapor and single-charged neutral vapor and ionized vapor at current chopping were investigated. It was found that the attenuation speed at current chopping decreases in the order of Cu, CuW, CuCr, CuBi and AgWC, the chopping current approximately decreases in the same order.
