摘要:
An inductive output tube (IOT) operates in a frequency range above 1000 MHz. An output window may be provided to separate a vacuum, portion of the IOT from an atmospheric pressure portion of the IOT, the output window being surrounded by a cooling air manifold, the manifold including an air input port and a plurality of apertures permitting cooling air to move from the port, through the manifold and into the atmospheric pressure portion of the IOT. The output cavity may include a liquid coolant input port; a lower circular coolant channel coupled to receive liquid coolant from the liquid coolant input port; a vertical coolant channel coupled to receive liquid coolant from the lower circular coolant channel; an upper circular coolant channel coupled to receive liquid coolant from the vertical coolant channel; and a liquid coolant exhaust port coupled to receive liquid coolant from the upper circular coolant channel.

The invention addresses a multi-channel induction accelerator with external channels, which in its broadest form includes an injector block (1), a drive system (4), a block of output systems (2), and a multi-channel induction accelerative block. The multi-channel induction accelerative block is formed of an aggregate of, linear induction acceleration blocks (including those that are placed parallel one with respect to the other), each acceleration block being formed from a sequence of linearly connected acceleration sections (7). Each acceleration section comprises one or more magnetic inductors (9) enveloped by a conductive screening (8). One or more inner accelerative channels (17) are placed axially within the inner parts of the conductive screening and have one or more azimuthally oriented slits (10). One or more channel electrodes are connected electrically with different parts of the inner parts of the conductive screening that are separated by the slit.

L'invention concerne les tubes électroniques amplificateurs fonctionnant en hyperfréquence. Le tube électronique comporte un fourreau tubulaire allongé (10) à l'intérieur duquel se développe un faisceau d'électrons (12), un carter (28) assurant le maintien mécanique du fourreau (10), et des moyens pour assurer un transfert thermique du fourreau (10) vers le carter (28) afin de refroidir le fourreau (10). Les moyens pour assurer le transfert thermique comportent une résine (36) remplissant un volume libre situé entre le fourreau (10) et le carter (28).

An inductive output tube, e.g., a KLYSTRODE, or a klystron, has a substantially hollow electron beam traversing a resonant cavity excited to the TM0x0 mode, where x is greater than 1.
摘要:
In a travelling-wave tube (20), a cylindrically-shaped slow-wave circuit cavity-defining member (34) is supported by and is thermomechanically bonded to a tubularly-configured vacuum wall member (32). The bonded joint comprises a pair of arcuate grooves (52) extending lengthwise of the slow-wave circuit and positioned diametrically opposite one another about the axis of the tube. A helical or wavy spring (54, 58) lies in each groove and is resiliently biased in intimate mechanical and thermal contact between the groove and the vacuum wall. The helical spring, in particular, can be used as a conduit for exhaust of gases from the travelling-wave tube during its fabrication.
