Versuche mit einem tiefgekühlten zwillingshohlkathoden interferometer-spektrometer—I

This work deals with the development of a set of twin hollow cathode tubes cooled by liquid air. The paper describes the construction of the hollow cathode device, the vacuum system and the current supply unit. The hollow cathode device is coupled to an interferometerspectrometer. The authors propose to use this arrangement for studying excitation processes in hollow cathode discharges and to apply it for emission spectrometric analysis.
