Hi!
I am doing a study into the early use of silicon diodes in radar and
communication equipment during the Second World War.
What I would be interested in is as follows:
-type numbers of the diodes
-name/type number of radar/communication equipment
-technical infor on those systems
-info on producers
-pictures of actual diodes, also "in" the circuits
-anecdotal stories about the actual use
-anything else!
The information will be used for an on-going study project related to
practical application of minerals (i.e. quartz) in industry and
technology.
(Quartz being the source for silicon, of course.)
So, since this is an aspect of a broader study, other
quartz/silicon-related
info
would be most appreciated, especially about early use of piezoelectric
quartz crystals in electronic equipment.
If you'd prefer, answering off-list is possible:
