Kathodenstrahlröhre zum Aufzeichnen schnell verlaufender Vorgänge mit einem rotierenden Strahl, der in Abhängigkeit von dem aufzunehmenden Vorgang senkrecht zu seiner Hauptbewegung abgelenkt wird, dadurch gekennzeichnet, daß die Ablenkung des Strahles senkrecht zu seiner Hauptbewegung durch das von einem gerade ausgestreckten stromdurchflossenen Leiter erzeugte magnetische Feld bewirkt wird, der im Kolben innerhalb des von dem rotierenden Strahl umgrenzten Raumes angeordnet ist.Cathode ray tube for recording fast-moving processes with a rotating beam which, depending on the process to be recorded, is perpendicular is deflected to its main movement, characterized in that the deflection of the beam is perpendicular to its Main movement caused by the magnetic field generated by a straight conductor through which current flows which is arranged in the piston within the space bounded by the rotating jet.

It has already been suggested. To use cathode ray tubes in the manner of the Braun tubes for recording fast-running processes and to design them in such a way that a rotating beam is deflected perpendicular to its main movement as a function of the process to be recorded. According to the proposal already made, two pairs of deflector plates arranged perpendicular to one another are used to generate the rotational movement, while a pair of concentric, cylindrical or conical capacitor plates are used to deflect the rotating beam perpendicular to the rotational movement, through the space between which the beam passes. Fig. 1 shows the circular path α described by the beam in such an arrangement and the drawing b corresponding to a regular curve in the form of a wavy line.

It is also known to have a cathode ray tube with two pairs of deflector plates in the Way to use that the two AbJenkplattepaare to generate the rotational movement of the electron beam and the voltage to be recorded between Cathode and anode is placed. A recording of the type shown in Fig. 1 then also results. at However, this known method results in fluctuations in the intensity of the electron beam and thus fluctuations in light intensity when the curve is plotted on a fluorescent screen.

According to the invention, to deflect the beam perpendicular to its rotating Main movement used a cathode ray tube, in which a straight stretched out current flowing through it Head is arranged in the piston within the space bounded by the rotating beam. In Fig. 2 is an embodiment of the invention shown. The basic rotating movement of the beam can be achieved by two pairs of plates. Instead of You can also use magnetic deflection coils, as indicated in Fig. 2 by 8 and 9. At 10 it's straightforward outstretched ladder. In such a tube the cathode ray an increased freedom of movement, so that even with going back and forth in a straight line Rays can be worked.
