Definitions
- the present invention relates to microwave tubes with longitudinal interaction, also called "0" type, with cavity.
- Longitudinal interaction microwave tube means a tube using a magnetic field focusing substantially parallel to the path of the beam electrons. These tubes call for the interaction of beam electrons in collective motion with a wave microwave.
- These tubes can be klystrons or wave tubes progressive with coupled cavities and their derivatives.
- a classic klystron has an electron gun that produces a long and thin electron beam through a succession of cavities interconnected by sliding tubes. At the end of the last cavity the electrons are collected in a coaxial collector with the beam. This collector heats up, it is cooled, for example, by making circulate at its periphery a coolant.
- a focusing device surrounds the cavities, it prevents the electron beam to diverge.
- This focusing device is often formed of an electromagnet in the shape of a hollow cylinder.
- a microwave wave to be amplified is introduced into the cavity closest to the cannon.
- the outlet cavity or cavity closest to the collector is intended to be connected to a member of use by via a transmission line, this transmission line conveying the amplified microwave wave towards the member of use.
- This transmission line is a rectangular, circular or coaxial.
- This waveguide is generally arranged transversely to the electron beam.
- the coupling between the output cavity and the waveguide is made through at least one orifice in the side wall of the cavity.
- a window can block the coupling hole. It is intended for let the extracted microwave wave pass while maintaining the vacuum thrust that reigns inside the cavity.
- the transmission line being connected to a side wall of the output cavity, the focusing device must take account of this connection and have an indentation there.
- the magnetic field is reduced and asymmetrical at the exit cavity while this is where we need it the most. As a result the electron beam is defocused.
- This transverse transmission line also causes a significant difficulty during the positioning of the tube. You have to slide the barrel-cavity-manifold assembly in the focusing device and adjust the relative position of the assembly and the device to fix the line of transmission. This operation is very delicate because of the masses put at stake and the fragility of the bond.
- the barrel-cavity-manifold assembly can weigh several hundred kilograms.
- the present invention aims to produce a microwave tube with longitudinal interaction with cavity which has neither asymmetry of the field magnetic, nor collector of limited size and which is very simple to assemble and reduced cost.
- the present invention proposes to make cohabit in the collector the microwave wave to extract and the electrons of the beam.
- the present invention relates to a microwave tube with longitudinal interaction with at least one directed electron beam along an axis, crossing a so-called outlet cavity in which it interacts with a microwave wave, this cavity having a terminal wall which separates from a collector, the electron beam entering the collector by at least one opening in the end wall, characterized in that the end wall further comprises at least one coupling member for couple the output cavity to the collector, the microwave wave in front circulate in the collector before being extracted therefrom.
- the coupling member can be an iris or a loop of coupling, for example.
- At least one obstacle can be provided in the collector microwave.
- the collector has a end opposite to the outlet cavity fitted with a junction flange intended to be connected to a transmission line to convey the wave microwave out of the collector.
- a microwave window is placed in the collector. She may be substantially transverse to the axis of the electron beam or else substantially parallel to the electron beam.
- the collector may contain successive partitions mounted in a baffle, in upstream of the window.
- Two successive partitions may have opposite portions. These portions can be edges or be larger.
- the window can have one of its faces covered with a material slightly conductive such as titanium, so as to allow the flow of electrical charges due to electronic bombardment.
- the collector can be externally equipped with means producing a magnetic field aimed at deflecting electrons before they don't reach the window.
- the collector may include a bent portion so that that the microwave wave is extracted substantially transversely.
- the window can be placed downstream of the angled portion of so as to be protected from electronic bombardment and to be accessible if cleaning is required.
- the collector can have a transition so that the cross section of the elements placed downstream is different from that of the part of the collector upstream.
- a section of waveguide attached to the collector can help form the bent portion, a bent waveguide can also be used.
- the collector can have a non-circular section as very often, but rectangular.
- the collector can be externally equipped with a cooling.
- Figure 1a shows a longitudinal section of a tube microwave according to the invention.
- Figure 1b is a section transverse along the axis AA.
- the tube shown is a klystron. It behaves so classic, a gun 1 producing a long and thin axis 2 electron beam XX '.
- the electron beam 2 crosses a succession of cavities C1, C2, C3, C4, C5. They are aligned along the axis XX '. They are separated by sliding tubes 3.
- the cavities C1, C2, C3, C4, C5 are surrounded by a focusing device 4.
- the cavity C1 closest to the barrel 1 is called the inlet cavity and the cavity C5 furthest from the barrel 1 is called the outlet cavity.
- a wave microwave to be amplified is introduced into the input cavity C1 using a coupling device 5. It will interact with the electrons who will give him part of their energy.
- the electrons in beam 2 after passing through the cavity of output C5 are collected in a collector 6.
- the collector 6 generally in the form of a hollow cylinder is shown substantially coaxial with the axis XX '.
- the collector 6 is externally equipped with a device for cooling 7. In the example described, this device operates by fluid circulation.
- the outlet cavity C5 has an end wall 8 which la separates from the collector 6. This end wall 8 has an orifice passage 11 for electrons.
- the manifold 6 and the output cavity C5 are coupled electromagnetically using at least one coupling member 9 located in the end wall 8 but separate from the passage orifice 11 for the electrons.
- the microwave wave propagates in the collector 6 where it then coexists with the electrons of beam 2.
- the coupling member 9 is an orifice or iris in the end wall 8 of the outlet cavity C5.
- the coupling is electrical between the output cavity C5 and the collector 6.
- the iris 9 cuts the current lines in the output cavity C5.
- An electric field is induced at the level of the iris and this field excites the electrical component of the propagation mode in the collector 6.
- This mode is preferably the TE11 circular fundamental mode because it propagates alone over a wide frequency range. It is possible to have use of other modes in collector 6, in particular using several orifices for coupling or at least one member for coupling a other type, for example a loop.
- FIGS. 1a, 1b a corner 12 is visible in the manifold 6 downstream of the end wall 8, it is opposite to the coupling member 9 relative to the orifice 11 for the passage of the electrons.
- a pawn a series of steps for example could be used to corner place.
- the depth of the collector 6 is conventionally fixed by the expansion of the electron beam 2 when the magnetic field reduced.
- the end wall 8 of the cavity of outlet in magnetic material, soft iron for example, the field magnetic then falls strongly in the collector 6 compared to what it was in the outlet cavity C5.
- the tubes of sliding are in non-magnetic material, copper for example.
- Figure 1c shows the equivalent electrical diagram of the coupling between the outlet cavity C5 and the manifold 6.
- the outlet cavity is equivalent to an R, L, C circuit in parallel.
- the coupling member 9 is equivalent to a first transformer and the microwave obstacle 12 to one second transformer.
- the collector 6 is designed to be connected to a line of transmission 10 at its end opposite the outlet cavity C5.
- This transmission line 10 is intended to convey the wave microwave extracted from the output cavity C5 and which has passed through the collector 6 to a user device (not shown).
- the line of transmission 10 is arranged in the extension of the manifold 6 substantially along the axis XX '.
- the manifold 6 ends with a flange of junction 14 to which the transmission line 10 is fixed.
- the transmission line transmission 10 can be a circular, rectangular or even waveguide coaxial. Exciting the circular fundamental mode in the collector has another advantage, it easily converts to TE10 mode rectangular which can be used in transmission line 10 if it is formed of a rectangular guide.
- a microwave tube operates under vacuum. Generally the user device and the transmission line are not working at the same pressure as the tube, they can operate at pressure atmospheric or at a higher pressure. A microwave window 15 of dielectric material is then used to maintain the vacuum at inside the tube while letting the microwave pass through the transmission line 10.
- the window 15 is placed in the collector 6, at its end opposite to the outlet cavity C5, upstream of the flange of junction 14. It is substantially transverse to the axis XX '.

- the electrons striking window 15 have several origins, there are those who entering the manifold 6 near the axis XX 'have not been deflected, those which are reflected by the collector wall as well as the electrons secondary emitted after an impact between a so-called primary electron and the wall of the collector. This bombardment causes an accumulation of charges on the window.

- the window 15 is always substantially transverse to axis XX 'and the transmission line (not shown) always directed along axis XX '.
- the waveguide portion 21 accommodating the window can have a different shape of cross section than that of manifold 6 and / or of different dimensions.

- the transition 20 transforms a circular guide into a rectangular guide.
- the collector 6 is externally equipped with means 22 producing a transverse magnetic field upstream of the window 15 of way to deflect the electrons passing through this area so that they do not reach window 15.

In the example shown, they have portions in vis-à-vis, these portions are edges 31 in the central part of the collector 6. It is also conceivable that two successive partitions 30 have larger portions opposite.
- partitions 30 are arranged towards the end of the manifold 6 opposite the outlet cavity C5, upstream of the window 15, in an area where the current of the electron beam is already well attenuated. These partitions 30 intercept electrons not yet collected regardless of their origin.
