Found at a Yard Sale?
Someone asks, What is it?
I surmise this was found at Freddy Roentgen’s yard sale, selling his grandfather’s dusty lab equipment. It’s an x-ray tube — boil off electrons, accelerate them and have them slam into the copper target, where they emit bremsstrahlung and also ionize the target, which will give some x-rays during the recombination if it involves inner-shell electrons. It’s unshielded, so it’s probably pretty old and/or taken out of a shielded device. I’d imagine a newer device to be more compact and with more recognizable connectors.

doesn’t look like it has been used much, or some of that copper would have been sputtered off to coat the inside of the vacuum envelope, and we would not be able to see in.
A newer device would also probably have a spinning tungsten anode.
