A vacuum spark discharge source with aluminum electrodes is constructed to obtain highly ionized aluminum line spectra in the 50-100 Å region. It is similar to BRV sources in having a trigger electrode to initiate the discharge ; it differs from them in that the radiation from the discharge channel is observed in the radial direction. The highest ionization stage observed is Typical spectra are shown in a form of densitometer trace. A simple plasma model is assumed to discuss the possibility of obtaining more aluminum lines in the 50-100 Å region.
