Day and night—the think tank on leak localization in action.
Honey bees can be trained to sniff out explosives such as TNT, so why not use them for localizing leaks within the ITER vacuum system? Or how about tiny flying robots that take off to explore the intestines of the system? Of course, there are also less fancy but nevertheless very efficient methods such as visible spectroscopy to detect the micron-sized (one millionth of a metre) leak in the system that could shut down the whole machine.
