development and pre-production of a valve. Other designations usually followed when in full production.

10. A ‘proximity fuse’ detonates an explosive device automatically at a predetermined distance from the target. Different proximity fuses are designed for
different targets, such as aircraft, missiles, ships and ground forces. They
provide a more sophisticated trigger mechanism than the common contact
fuse. Along with radar, the proximity fuse is considered one of the most
important technological military innovations of World War II. (From
Wikipedia).
11. There is no doubt that Randall and Boot invented a cavity magnetron, but
they were not the first to do so. They were preceded by the work of Samuel in
the USA, Aleksereff and Malearoff in Russia, and by work in Japan. But
Randall and Boot were almost certainly unaware of this prior work. however,
their design, with the anode being part of the vacuum envelope and the
output coupling loop inside a cavity, made the high-power cavity magnetron
possible. This design was the basis of all further microwave magnetrons. The
development was to revolutionise radar and was the key element in making
microwave radar possible.
