Abstract
A description is given for the modification of the Bausch & Lomb dual grating spectrograph so that it may be used to directly measure longitudinal spectral line profiles with fixed phototube detectors. These measurements are often necessary in plasma diagnostics. The modified instrument has a single, compact, out of the way drive system that tilts the grating. This allows any number of lines to be recorded simultaneously. The time for scanning a cross section in the radiating source is on the order of 30 sec.Keywords
