Very cool I think, arguably a/the pinnacle of tube technology. RCA abandoned it to concentrate on TV stuff, much to von Neumann's disgust.

Great site here http://www.rcaselectron.com/

Wow, looking at the AFCRC (Air Force Cambridge Research Center Memory System), 14ft of rack and 6kW consumption for 5kb of RAM? It's a shame they didn't develop the 4kb part a bit quicker.

The link below is to a video that has a good look at the electron gun of a therapeutic electron linear accelerator.  The spooky parts of these machines are the copper microwave cavities that accelerate the electrons.
