 | - the mathematical models and software packages on Delphy
was created for account and optimization of parameters TWT-O and BWO on based of
equations of movement of large partiales with provision for following factors: influence
of field of a space charge, stratification of an electronic beams, excitation of
harmonicses on multiple frequency of a signal); |
| - designed and motivated efficient method of finding
nearly-optimum on effisiency the law of changing a cool phase velocity along SS TWT-O -
method of synchronous electron; |
| - the method of account of dispersing performances spiral
SS with dielectric rods fastening a spiral developed; |
| - with the help of of method synchronous electron it is
obtained the optimum smooth law of a modification of a cold phase velocity along CN TWT-O,
for which the efficiency up to 80% is ensured; |
| - offered and is investigated TWT-O with spiral electron
beams and regular SS, in which the synchronism along area of interaction is supported by a
smooth modification of a magnetic focusing field. With the help of synchronous
electron method the optimum law of a modification of a magnetic field is found and
parameters such of TWT-O which for want of is achieved efficiency up to 72%. |
| - the method and software package for account TWT-O with
SS as a section of an irregular goffered waveguide developed. The conclusion of the
equations of excitation bases on map of an internal surface of an irregular corrugated
waveguide to the regular cylinder of a single radius and projective method Galerkin for
definition of the equations for amplitudes of connected waves excited in a waveguide by a
system of specific currents. The optimum structures of the corrugated waveguide and
parameters such of TWT-O with efficiency up to 80% are obtained. |
| - detected and investigeted the effect of auto adjustment
of slowing of a phase velocity in TWT-O with regular nonlinear SS which have a dielectric
insertion. which The dielectric permeability of such dielectric insertion is varies
with a modification of amplitude of microwaves. The optimum parameters such of TWT-O
are found and the efficiency up to 68% is achieved. |
| - on base partial optimization of profile of slow wave
structure of the relativistic BWO it had brrn shown that it's efficiency reach 40%,
efficiency of the reflecting TWT - oscillator reach 60%; in both cases the transformation
of foward and backward waves in regular or irragular corrugated waveguides play an
impotant role. |
