The Magnetron Valve by G. H. Davis
A set of diagrams demonstrating what a magnetron valve is, and why it is of such importance to radar. The magnetron valve was used in the Second World War to give Allied forces superior radars, and, after being offered to the USA to secure their support, it was described by America as " the most valuable cargo ever brought to our shores". It should be noted that the prototype magnetron valve was around six hundred times more powerful than anything in American production.
