“…Studies of this type on pulsed discharges, including sparks, require resolution in time as well as in space, and are therefore more difficult. Bardocz and Voros considered the methods for determining spark plasma temperatures from relative line intensities (31), Stark broadening (29), and wavelength shifts of lines (28); they also (SO) described the spatial and temporal variation of spark plasma temperature as determined from relative line intensities in time-resolved spectra.…”
