  • Publication number: 20240097408
    Abstract: A Marx configuration has a housing surrounding an interior, and a Marx generator arranged in the interior. The Marx generator has a plurality of capacitor stages connected in series, each having at least one first and one second voltage terminal, and respective cross branches. Each two adjacent capacitor stages between the first terminal of the preceding and the second terminal of the following capacitor stage are connected by one of the cross branches. Each of the cross branches contains a spark gap, a sealed gas space for an insulating gas for the spark gaps which are arranged in the interior and at least two of the spark gaps. All spark gaps are arranged in a respective gas space, and the interior contains a sealed fluid space for a cooling fluid for the Marx generator. A base support disposed in the interior and surrounds the gas space partially.

  • Patent number: 8796928
    Abstract: In order to increase a service life of a microwave generator, a resonator configuration for a microwave generator has a hollow cylindrical electrical conductor positioned inside a housing, a first electrode, and a second electrode. Two electrodes are spaced apart from one another and form a spark gap in the region of the conductor. A contact element is provided for making electrical contact between the conductor and the first electrode. The position of the first electrode can be adjusted to modify a length of the spark gap. Furthermore, the contact element is electrically connected to the first electrode or its holder so as to resist movement so that the opposing contact surfaces remain in contact even when the position of the first electrode is adjusted with respect to the second electrode. The contact element is configured to be deformable, preferably elastically deformable, for this purpose.

  • Patent number: 8436493
    Abstract: A microwave generator, which includes a housing having two mutually opposite electrodes which are separated via an electrode intermediate space which is filled with a dielectric, and with the electrodes having a spark gap between them, which breaks down in order to emit microwaves when a high voltage is applied. The electrode intermediate space (13, 13a, 13b) can be at least partially filled with a second dielectric (15, 15a, 15b), which has a different dielectric constant compared with that of the first dielectric (14, 14a, 14b) which is located between the electrodes (6, 7) in order to vary the microwave frequency, whereby the second dielectric (15, 15a, 15b) is held in a reservoir (17, 17a, 17b) which communicates with the electrode intermediate space (13, 13a, 13b).

  • Patent number: 7439677
    Abstract: A microwave generator having a central electrode (14) which at the front end has a radiating element (22) and an external electrode (18) which coaxially surrounds the central electrode (14) along an axially extending resonator portion (16), wherein the two electrodes (14 and 18) are of a rotationally symmetrical configuration and define a spark gap (62) which sparks across when a high voltage is applied and radiates microwaves by way of the resonator portion (16) and the radiating element (22) of the central electrode (14). The spark gap (62) is in the form of an annular spark gap, which is determined by a connection element (26) which projects at the rear end axially centrally away from the central electrode (14) and an annular edge (44) of the external electrode (18), the edge being provided coaxially with respect to the connection element (26). The central electrode (14) and the external electrode (18) are arranged in a housing sleeve (12) of an electrically insulating material.

  • Patent number: 7375444
    Abstract: A microwave generator (11) has a parallel connection of series connections of uncontrolled discharge spark gaps (13) and charge storage means (12) which are charged up by way of charging resistors (17) and an inductor (19) common to all parallel connections, from a high voltage generator (26), until the respective spark gaps (13) short-circuit by way of arcs and the storage means (12) are discharged again by way of the inductor (19). The oscillating short-circuit currents which thus occur in stochastic steep-edged manner and which are superimposed on each other in the inductor (19) are emitted by way of an antenna (21) connected in single-pole manner thereto in the form of a high-energy microwave spectrum which is wide-band in accordance with the arc switching speed, with a spectral key point which is determined by the inductor (19).

  • Patent number: 7002300
    Abstract: Intensive microwave radiation in particular of great band width and energy over a relatively long period of time in the form of long pulse packets with a high pulse repetition frequency and a very high frequency spectrum can be achieved if microwave irradiation is effected during the discharge of a capacitive high-voltage generator (35) by way of the antenna (26) into a series of successive capacitors (13) to be connected in parallel. They are preferably constructed in the form of a concentric stack, connected to the antenna (26), of which the outer electrodes (16) which are at a reference potential are in the form of a continuous tube within which annular electrodes (15) are disposed on a carrier (20) in axially spaced relationship with each other in such a way that at the same time they act as the electrodes of arc switches (39) for successively switching on subsequent capacitors (13).
