The operation principle of the present invention is: the relativistic electron beam of negative electrode generation and the TM determined by slow-wave structure01Pattern
Electromagnetic wave carries out restrainting wave interaction, produces High-Power Microwave and radiate via output waveguide.
Compared with prior art, the present invention is used to can reach techniques below effect:
(1) using factory's font collector, Main Function is as follows:
A () factory font collector utilizes lower end open-mouth to introduce electron beam, utilize the inwall at upper end closed to collect remnants
Electron beam.Through bundle wave interaction, electron beam reduces, again plus collector radius because losing energy (giving microwave field) speed
Relatively big, therefore dissipated when residual electrons arrives at collector inwall, the electron density of bombardment collector inwall substantially reduces.Cause
This, can weaken the secondary electron produced because of the beam bombardment inwall impact on output microwave pulsewidth, and suppressor pulse shortens existing
As, it is advantageously implemented long pulse；
B () is by regulation factory's font collector upper end, the width of lower end and the width of step, thus it is possible to vary high power is micro-
The discontinuity regulation phase place of wave source end, strengthens the interaction between electron beam and electromagnetic wave.From Fig. 5～7, adjust
Joint factory's font collector upper end, the width of lower end and the width of step, halved tie ripple effect can produce the peak with optimal effectiveness
Value.
(2) using 1 buncher, Main Function is as follows:
Buncher surface a () optimizes after has stronger axial electric field, can interact with electron beam, electricity
Sub-beam energy gives microwave field, improves power conversion efficiency.From Fig. 8～9, regulation buncher width and outer radius, energy
Halved tie ripple effect produces the peak value with optimal effectiveness.
When () electron beam transmits in buncher b, the velocity modulation that electron beam obtains in device initial segment is converted into
Density modulation and form clustering, at device rear part, the Shu Yubo with preferable cybotactic state will occur effective interaction, therefore
Power conversion efficiency can be improved.From figure 10, it is seen that at device rear part, electron beam has preferable cybotactic state.
(3) using 1 rearmounted resonator cavity to increase reflection, Main Function is as follows:
A the good electron beam of () clustering is when rearmounted chamber, the potential energy of electron beam reduces rapidly, and electron beam kinetic energy increases rapidly
Greatly, the most accelerated, it means that electron beam can give microwave field energy further, be conducive to improving power conversion efficiency；
B the rearmounted resonator cavity after () optimization is conducive to improving the quality factor of cavity, can improve Shu Bo at a resonant condition
Functioning efficiency, can realize efficient microwave excitation in the case of slow wave blade number is less, it is ensured that realize miniaturization with efficient
Rate.
(4) using 2 preposition resonator cavitys, Main Function is as follows:
(a) compared with only 1 preposition resonator cavity, utilize 2 optimized after preposition resonator cavity can be to diode
The reflection coefficient of the microwave of direction, district transmission is 1, can realize total reflection；
B (), compared with only 1 preposition resonator cavity, uses 2 preposition cavity resonator structures, the footpath of electron beam distance resonator cavity
Can both be avoided that electron beam scraping or bombarded preposition resonator cavity, penetrating of housing surface can have been weakened again more greatly to apart from optimized
Frequently field intensity, thus can effectively weaken the microwave pulsewidth caused due to the expanded radially of cathode plasma and shorten, favorably
In realizing the output of long pulse microwave.From Figure 11～13, using 1 preposition resonator cavity, housing surface high field is 1.4MV/
Cm, after experiment, obvious with the vestige of rf arcing by electron beam scraping on the right side of preposition resonator cavity, now microwave pulsewidth 150ns～
About 160ns；From Figure 14～16,2 preposition resonator cavitys, housing surface high field are used to be reduced to 0.9MV/cm, experiment
After, cut-off right side of neck is inconspicuous with the vestige of rf arcing by electron beam scraping, now microwave pulsewidth 200ns～about 210ns.
Therefore, use 2 preposition reflection cavities to increase the radial distance of electron beam range cutoff neck, i.e. avoid electron beam scraping or bombardment,
Weaken again device internal radio frequency field, beneficially long pulse microwave output.
C () can carry out more sufficiently premodulated to electron beam, be conducive to bundle wave interaction subsequently, improves device
Power conversion efficiency.With use compared with multiple (more than 3) preposition resonator cavity, utilize that 2 preposition resonator cavitys bring intrinsic shakes
Swing pattern less, it is not easy to produce mode competition, and the miniaturization of beneficially device.
(5) reflector is used, by width and the width on inclined-plane of regulation reflector lower end, thus it is possible to vary High-Power Microwave
The discontinuity regulation phase place of source end, strengthens the interaction between electron beam and electromagnetic wave.
