Helium is an inert gas with low background noise, small molecular weight, and low viscosity. It easily passes through leaks and diffuses easily. When helium ions are emitted from a helium source, they propagate in a vacuum environment. When passing through a leak, some helium ions escape through the leak, thus enabling the detection of the leak.
