MAGNETIC SYSTEMS OF MAGNETRONS
|
The issues of thermal stability in development of magnetic
systems of magnetrons are similar to those of TWT.
Insufficient heat removal from the magnetic system during
operation can lead to the output frequency drift. This drift
is proportional to the value of the reversible temperature
coefficient of induction which characterizes the magnetic
material.
However, Nd-Fe-B magnets are successfully applied in commercial
magnetic systems.

Magnetic system "Cyclamen" produced according to
the ÌÀÅÐ.684116.112 technical specifications provides the
longitudinal component of magnetic induction in the range
165 - 230 mTesla (depending on the number of tuning
bridges). This system has been developed for ÌÈ 456 pulsed
magnetron with output power Ðout = 2.5 MWt,
Ðav = 5 kWt, frequency 2800 ± 10 MHz,
and t = 6 mks for medical applications.
