Abstract: In Germany the cathode ray tube has assumed a definite though not very important role in the field of sound reproduction, and in television it has become of such importance that mechanical methods of scanning are rarely considered nowadays. The paper describes a new high-vacuum cathode ray tube especially designed for recording sound, the purpose of the development being to avoid the disadvantages inherent in such tubes currently used. The fluorescent line required for recording is produced by means of an electroöptical system in which a controlled accelerating voltage in the path of the electrons from the cathode constitutes the “lens electrode” and achieves the focusing action. The characteristics of the tube are described in detail.
