July 1940 the Battle of Britain was raging and France
had already fallen and so the idea seemed much more
palatable. Thus a team of 7, led by Tizard was in Washington
by 12th September to begin discussions.All three armed
services were represented and 'Taffy'Bowen was there
specifically to discuss radar. He was allowed to take
'Magnetron Number 12' with him. The Magnetron had only
been sent to TRE Worth some 6 weeks earlier.
mission established that Britain was 'in the lead' on
most counts but that certain aspects of American radar
were more advanced. It was the Magnetron however, that
was greeted with the greatest enthusiasm. Initially,
a new 'Microwave Committee' was set up with Dr Alfred
Loomis as Chairman. It was this man who played the decisive
role in converting US radar to centimetric wavelengths.
was soon agreed that the microwave committee would sponsor
rapid production of the Magnetron and that the Bell
Telephone Company should carry out the work. They produced
the first 30 in October 1940 and by the end of the war
well over a million US Magnetrons had been manufactured.
the Tizard mission was hailed as a success it is odd
that on his return to London on the 8th October 1940;
he found that his job no longer existed.
