[ARC5] Japanese technology

[Bill Fuqua]

    Radar technology was based on triode tube oscillators until the British 
developed the multicavity magnetron.
Once they got a working model they brought it to the US and in 
collaboration with the US the first modern
radar was developed. I talked with Norman Ramsey about 30 years ago about 
this. He was involved in the
development of the "modern" radar when the prototype magnetron was delivered.
He died in November last year. A  few years after meeting  him he go t the 
Nobel Prize for developing the first
atomic clock.
