Description |
This paper presents 3-D electromagnetic
simulation of resonant system of a 2.6 MW, 2.998 GHz
tunable pulse magnetron using MAGIC3-D Code. This
resonant system is a twelve resonator hole and slot type
structure with echelon type strapping. Other parts include
coupling loops, output seal and tuning mechanism.
Coupling is through radial mounted double loop with a
dome type glass window. The capacitive tuner, connected to
one of the side resonator, consists of metal bellow and a
metal piston that can be moved in radial direction. π-mode
frequency has been computed simulating position of the
tuner to give minimum and maximum frequency values.
Corresponding π-mode frequencies found are 2.953GHz
and 2.970 GHz giving predicted tuning range of 17MHz.
The dispersion characteristic has also been obtained. The
cold test model of the magnetron has been fabricated and
experimentally characterized. Performance chart has been
plotted using in-house computer program. Simulation
results have been compared with experimental values and
have been found in good agreement except ‘Q’ values.
