Creating X-rays with a standard vacuum tube https://tube.loping.net/videos/watch/d1a75a5c-c223-4bc8-ab0f-1bc7ded326b2 I forced an RCA 811A tube to produce some X-rays by operating the tube in cold-cathode mode at about 20KV and 150uA. The glass fluoresces nicely, but I didn't get any light from my X-ray intensifier cassette.
