Abstract:

During experiments with high-temperature plasma investigation of spectra of fast-flowing chemical reactions, as well as other aspects, make it necessary to record the form of spectral lines in periods shorter than the time duration of the process being investigated. Such demands require a device with high time resolution and large amplification. Spectral lines can be used in a number of cases to determine density and temperature of plasma. In the article a description is given of an improved device, a double converter, its construction, and principles of operation. The device tested showed that with its help it becomes possible to produce registration of contours of spectral lines in times up to 10 to the -8th power s and less. The double converter also permits multiple recording of both separate lines and also sections of spectrum, and it can be used for study of flow in cylindrically symmetric objects. Finally, it can serve as a photomultiplier with improved signal-to-noise ratio during study of weakly luminescent objects. Author
