X-rays of vacuum tubes?  Nick Veasey is a photographer that likes to do things a little differently.  Rather than using a camera, he X-rays everything.  Mentioned in an article published by Wired, Veasey has taken x-rays of several thousand items over the years.

From Wired: “Veasey is one of the few people who know how hard it is to get a crisp x-ray of a vacuum tube. For starters, the object has very little mass to absorb the radiation. And because the edges of the tube curve away from the film, the x-rays get scattered about, causing distortion. So Veasey shot this tube in a series of 10-second bursts. The succession of blasts builds up the energy necessary to capture the fine details, while their short duration keeps background radiation from clouding the picture.”
