Here's a simple question with a very frustrating lack of answer: When was the carcinotron deployed? Technically a carcinotron is a backward-wave oscilloscope in which an electron beam was passed through a strong radio frequency field. The upshot is a strong output radio frequency emission, which can be in the frequency range of a microwave rada. Altering the modifying rf field allows the output emission to be rapidly "swept" across the entire emission band of a given radar, permitting what looks like universal jamming.
I honestly don't know much about the subject, and I am very glad that radio engineering enthusiasts continue to update the relevant Wikipedia articles. We thus now know that one kind of backward wave oscilloscope, also called, or a variant, of the so-called travelling-wave tube, which was invented at and by, among other people and places (the patent wars are strong with this one), in 1943, by Austrian Jewish emigre Rudolf Kompfner, then working at the Admiralty Research Laboratory. Kompfner's patents were gazetted starting in 1957, while the first published work on the backward wave oscilloscope was published in 1953, and the Wiki article on the TWT points us at the Hughes Aircraft Electron Tube Laboratory, or Microwave Tube Division in Culver City, California, a research facility that is new to me as of right now, and which has been recently folded into Stellant Systems along with many other ancestors. All that institutional history, gone, like tears in the rain.
The upshot is that, in Britain or in America, the carcinotron specifically, the revolutionary airborne radar jamming device that, in the Thomson incarnation above, weighed no less than 25kg, went into production/service in "the 1950s."
This is, I have to say, an unsatisfyingly vague dating for what seems to have been a very quite technological panic over the future of air defence radars. It seems like a reasonable guess that its appearance is linked to the very substantial "ECM suite" on the V-bombers, upon which so much faith was, apparently, justifiably placed. One assumes that it went into the Canberra, B-47, and B-52, as well. One infers that it might have been a problem for the SAGE rollout and for the upgrading of Britain's radar defences. One wonders what the implications of the new technology were for the radar station at CFS Holberg, up the road from my small hometown and something of a big deal in our sparsely populated region, in which every rationale for the existence of a community was to be celebrated. There's not much to be said about it beyond that except that evidently there's a crisis in air defence radar going on behind the scenes right now in March of 1953, but shh, because it is a secret, wilderness of mirrors and all of that stuff. If you hide how flustered you are from the Reds, maybe they won't notice the carcinotron before some counter-measures emerge!
Remember when Americans took the train? I don't, either. I'm only 58, and too young for that stuff. The title's historic, too. No-one likes it hot any more. We've got enough heat, amiright?
