I've considered using them in pre-amplifiers for particle beam position pick-ups in accelerators, because they're rad- hard. I never actually did it though. It would have been necessary to shield them from magnetic fields, which is a pain, and the limited lifetime would have been a nuisance, anyway. In the end, I decided to use semiconductor circuitry, kept at some distance from the beam pipe. Jeroen Belleman
