On 21 February 1940, John Randall and Harry Boot first ran their cavity magnetron at 10 cm ( 3 GHz ).
23.
The aircraft's highly secret cavity magnetron is recovered the next day by a TRE team from RAF Defford led by Bernard Lovell.
24.
Green Satin was thus based on a simple cavity magnetron generator, rather than the more accurate traveling wave tube solutions like the klystron.
25.
During the Second World War he worked in the Radiophysics Laboratory in Sydney, where he produced a laboratory model of a cavity magnetron.
26.
:: : : Can you cite any evidence that cavity magnetron design with respect to frequency has ever been linked to planned obsolescence?
27.
Centimetric radar, made possible by the cavity magnetron, allowed for the detection of much smaller objects and the use of much smaller antennas.
28.
This was especially true after late 1940, when Great Britain shared its electronic secrets ( including the cavity magnetron ) during the Tizard Mission.
29.
Since then, many millions of cavity magnetrons have been manufactured; while some have been for radar the vast majority have been for microwave ovens.
30.
All of the-270 versions were later replaced by newer microwave units after the cavity magnetron was introduced to the US during the Tizard Mission.
