a Study of the Analogy Between Ion and Light Spectrometry Leading to the Development of a New Dynamic Mass Spectrograph.

Efforts were directed toward finding a new charge to mass (q/m) path stability field (analogous to wave length stability path in optical spectrometry), or combination of fields, where (q/m) will be determined by path stability and the velocity by time of flight methods. The resulting spectrometer was an electro-dynamic spectrograph having a (q/m) path stability over the whole range of ions analyzed. This spectrograph and some of the experimental results are described. An optical spectrograph, analogous to ion optical spectrographs, having a space varying index of refraction, is proposed. It is clearly seen here that the analogy serves as a vehicle for transferring solutions from one field to another. A variety of other applications, stimulated by looking at both the ion and light optics, are discussed in the text and appendices.
