After ionizing the helium, we’ll count those ions as it impacts the actual detector. Over time, this is what gives us the measured leak rate. Because of this system, we can detect the smallest leak ...
The cold helium gas also helps take thermal stealth to a whole new level. Exhaust plumes cooled by 1,327 degrees Celsius (2,420 Fahrenheit) can technically evade detection by almost any infrared ...
