Definitions

  • the present invention relates to vacuum and ultra-vacuum tight microwave windows, used in principle at the output of a power electron tube to transmit microwave electromagnetic energy between the interior of the tube (under high vacuum) and the tube. 'outside (in an atmospheric environment for example).
  • the tube can in particular be an amplifier such as a traveling wave tube, acronym TOP in French or acronym TWT in English for "traveling wave tube"), or a klystron for example. It can also be an oscillator (magnetron, etc.). Typically, one wishes to send the amplified energy inside the tube to a waveguide which contains air.
  • the microwave window ensures the free passage, at least in a given frequency band, of electromagnetic energy towards the waveguide while maintaining the seal of the vacuum inside the tube.
  • the windows comprise a flat disc of insulating dielectric, through which the electromagnetic energy passes.
  • this disc is made of alumina or another ceramic having not only very good dielectric properties but also good thermal conductivity and good resistance to high temperatures and to strong temperature gradients. Indeed, for tubes of high power and operating with high electric fields, the passage of energy generates losses in the dielectric, therefore significant heating.
  • the tubes concerned here can provide powers of several tens of kilowatts.
  • the dielectric disc can typically have dimensions of around ten centimeters in diameter for a thickness of 1 millimeter to a few millimeters.
  • the dielectric disc is brazed over its entire periphery against the inner surface of a metallic cylindrical skirt (generally copper) which surrounds it.
  • An aim of the invention is to make it possible to increase the powers at the output of a microwave window, and therefore in particular to improve the resistance to thermal stresses while retaining the advantages of existing windows.
  • a microwave window comprising a dielectric disc, a main metal skirt brazed all around the periphery of the dielectric disc and a prestressing ring surrounding in contact the main metal skirt around the periphery of the dielectric disc and exerting at rest, over the entire periphery of the dielectric disc, a radial compressive stress directed towards the center of the dielectric disc, said prestressing ring comprising a set of at least one cooling channel drilled in the longitudinal direction of the preload ring.
  • the solution provided makes it possible to create a cooling circuit around the dielectric disc and a prestressing.
  • This invention makes it possible to improve the mechanical resistance in extension in the dielectric material. On the other hand, by removing the calories due to microwave losses in the dielectric material, the stresses are thereby minimized.
  • Another advantage is the fact of having a window which remains cold while protecting itself from the risk of thermal shock by too large a temperature difference between the outside and the center of the dielectric material.
  • the assembly is carried out in a single step such as for example by brazing and therefore makes it possible to minimize manufacturing costs.
  • this assembly can be baked in the vicinity of 600 ° C. because the prestressing ring is not adherent and therefore can relax during this thermal cycle.
  • the preload ring includes an annular region and is part of a preload assembly pressing on an exterior surface of the main metal skirt around the periphery of the dielectric disc.
  • the prestressing ring is made of stainless steel.
  • Stainless steel is well suited to water circuits with good mechanical strength.
  • the prestressing assembly comprises at least part of a cooling circuit comprising the assembly of at least one cooling channel.
  • the prestressing assembly comprises elements made of at least one metal which is more rigid than that of the main metal skirt.
  • the microwave window further comprises an additional metal skirt internal to the main metal skirt.
  • the thickness of the prestressing ring is between 2 and 10 mm.
  • the thickness of the pre-stressing ring depends on the diameter of the channels and the required heat transfer fluid flow rate.
  • the microwave window comprises a lubricating substance interposed between the preload ring and the main metal skirt, to prevent sintering between the preload ring and the main metal skirt in the event of an increase in temperature of the ring. prestressing.
  • the lubricating substance is preferably graphite, since it is particularly well suited.
  • the dielectric disc is made of ceramic, since ceramic has a limited cost.
  • the main metal skirt is made of copper, the copper making it possible to adapt to the expansions of the materials, and being a good electromagnetic conductor.
  • the prestressing ring comprises a set of a plurality of cooling channels.
  • said cooling channels have an identical diameter of between 0.5 and 4 mm, which allows a homogeneous distribution of the prestress.
  • the cooling channels are evenly spaced.
  • a method of manufacturing a microwave window comprising placing a dielectric disc inside a main metal skirt, with a brazing material, and with a clearance. between the periphery of the disc and the main metal skirt, in placing the dielectric disc and the main metal skirt inside a preload assembly comprising a ring prestressing pierced with a set of at least one cooling channel and surrounding the main metal skirt over the entire periphery of the dielectric disc, a clearance being provided between the preload ring and the main metal skirt, to place a brazing ring around the preload ring with a clearance between the hoop and the preload ring, the material of the hoop having a lower coefficient of expansion than that of the preload ring, to carry the whole hoop, preload ring, skirt main metal and dielectric disc at a temperature ensuring the brazing of the dielectric disc in the main metal skirt, and to be allowed to cool, the cooling ensuring a preload in radial compression of
  • a lubricating substance preferably graphite, is interposed between the prestressing ring and the main metal skirt, preventing sintering. between the preload ring and the main metal skirt in the event of an increase in the temperature of the ring.
  • the figures 1 to 3 schematically illustrate a method of manufacturing a microwave window, according to one aspect of the invention.
  • the method of manufacturing a microwave window 1 comprising placing a dielectric disc 2 inside a main metal skirt 3 or window skirt, with a brazing material, and with a small clearance 4 between the periphery of the disc dielectric 2 and the main metal skirt 3, to place the dielectric disc 2 and the main metal skirt 3 inside a preload assembly 5.
  • the preload assembly 5 comprises a preload ring 6 pierced with an assembly of at least one cooling channel 7 and surrounding the main metal skirt 3 over the entire periphery of the dielectric disc 2, a clearance 8 being provided between the ring prestressing 6 and the main metal skirt 3.
  • the prestressing ring (6) is annular in shape.
  • a brazing hoop 9 is placed around the preload ring 6 with a clearance 10 between the hoop 9 and the preload ring 6, the material of the hoop 9 having a lower coefficient of expansion than that of the preload ring 6 .
  • the hoop 9, preload ring 6, main metal skirt 3 and dielectric disc 2 assembly are brought to a temperature ensuring the brazing of the dielectric disc 2 in the main metal skirt 3, typically greater than 700 ° C, and to be left to cool, the cooling providing a radial compression preload of the preload ring 6 on the main metal skirt 3 and on the dielectric disc 2.
  • the microwave window remains open and can receive a flange on each side to ensure the connection, for example to a tube outlet on one side and to the flange or to the customer connection on the other side, or even to place on each side, in the in the case of a microwave transmission window, a client interface on either side of the cooled prestressed window.
  • the prestressing assembly 5 comprises at least part of a cooling circuit, not shown, comprising the cooling channels 7.
  • the prestressing assembly 5 comprises two inputs / outputs 14 and 15 which can be connected to a circuit. cooling.
  • the size, shape and spacing of the channels 7 makes it possible to adjust on the one hand the flow rate of the coolant heat transfer fluid, such as water or water and glycol, and on the other hand to adjust the desired level of prestressing.
  • the coolant heat transfer fluid such as water or water and glycol
  • the figure 1 therefore illustrates the assembly of the elements of the microwave window before brazing.
  • the parts of the brazing tool make it possible to ensure the brazing clearances.
  • the prestressing is carried out during assembly, for example by brazing, of the assembly at high temperature, typically greater than 700 ° C.
  • the hoop 9 in a material whose coefficient of expansion is lower than that of the material of the dielectric disc, makes it possible to progressively deform the cooling circuit and the outer diameter of the preload ring 6 in order to adjust the assembly parameters.
  • the figure 2 therefore illustrates the assembly of the elements of the microwave window during soldering.
  • the preload ring 6 imposes a compressive stress on the main metal skirt / dielectric disc 6/2 assembly depending on its thickness, on the volume of the cooling circuit (set of channels 7) and mechanical properties of the material of the prestressing ring 6.
