SU69815A1 - Electron beam lamp - Google Patents

Description

The design of the first electron-beam lamp of the klystron is cumbersome and inconvenient in production and operation.

The invention proposes a new design of an electron beam modulating electron velocity lamp. This design is simpler to manufacture, has a smaller number of vacuum junctions, eliminates the need for the electron beam to be focused by a magnetic field, provides a greater amount of heat, and is more portable and convenient to use.

The listed advantages of the proposed lamp are ensured by the fact that its volume contours are formed in one common metal cylinder by means of a transverse disk partition, through the central part of which comes the drift channel tube.

To provide feedback between the contours, the partition has one or more openings, and for setting the contours, the end walls of the cylinder are made flexible.

The circuit and design features of the proposed lamp are illustrated in FIG. I-6.

FIG. I lamp depicted in schematic form. Here the following notation is taken: / - cylinder forming the lamp body; 2 - partition, dividing the cylinder into two resonating volumes; 3 - drift channel tube;

4 is a hole for feedback;

5- energy output; 6 - electron gun.

The lamp is as follows. The electrons ejected from the cathode are accelerated in the space between the cathode and the first grid 7. In the first resonator between the first grid 7 and the second grid 8, the electrune speeds are modulated. In the drift channel 3, the fast electrons overtake the slow ones, and the direct current is converted to alternating current. In the second resonator between the third grid 9 and the end wall of the cylinder 10, the kinetic energy of the electrons is converted into the energy of high-frequency vibrations. The main part of the high frequency energy is output through the opening 5 and a small part passes through the opening 4 for modulation.

FIG. 2 shows a section of the generator lamp of the above construction.

FIG. 3 schematically shows modifications that can be used not only in generator lamps, as shown in FIG. 3, but in all other types of electron-beam lamps.

FIG. 4 shows a high frequency amplifier circuit; in fig. 5 is a diagram of a regenerative amplifier and FIG. 6 is a frequency multiplier circuit.
