Problems solved by technology

One of the most direct ways of bundling is: bundling multiple completely independent high-power microwave devices together. This way not only requires bulky, difficult synchronization, but the probability of power increase is extremely low; while the other way is: a single pulse The power source drives multiple independent high-power microwave devices, which can increase the power, but requires a larger volume

Embodiment 2

[0025] Such as figure 2 As shown, the difference from Example 1 is that one of the cathode branches is branched again, and the cathode branch is divided into two output cathode branches. Similarly, the corresponding outer cylinder structure is adjusted accordingly. Finally, ensure that each output cathode branch is compatible with an outer cylinder, and a complete output cathode and anode are newly produced.

[0026] In this embodiment, by using the combined electric vacuum diode, the bundling of three high-power microwave devices can be realized, and the parallel driving of the cathodes of the three high-power microwave devices can be achieved.

[0027] The connection relationship is that the right end of the outer cylinder is connected to the cylinders (9, 10, 11) of the three devices, the left end of the outer cylinder is connected to the output outer cylinder of the external high-voltage pulse power supply, and the left end of the shielding ring on the power source side i...

Abstract

The present invention discloses a combined-type vacuum diode used for a high-power microwave source. The combined-type vacuum diode comprises a large outer cylinder which may be connected with the high-power microwave source, a microwave source shielding ring, an insulator, a vacuum side shielding ring, a cathode pedestal, cathodes, a small outer cylinder and anodes. According to the combined-type vacuum diode, a plurality of cathode and anode structures share one insulator, and thus the cathode and anode structures or high-power microwave devices are combined for parallel drive to generate high-power electron beams.

Description

technical field [0001] The invention belongs to the field of microwave electronics, and specifically relates to a combined electric vacuum diode. The invention can be applied to the development of high-power microwave sources in the high-power microwave technology field. Background technique [0002] With the development of high-power microwave technology, the output microwave power of high-power microwave sources continues to increase. However, due to size and volume constraints, it will become more difficult to further increase the output power of a single microwave device. For this reason, a greater output microwave power can be achieved by bundling multiple high-power microwave devices. One of the most direct ways of bundling is: bundling multiple completely independent high-power microwave devices together. This way not only requires bulky, difficult synchronization, but the probability of power increase is extremely low; while the other way is: a single pulse The powe...
