🔍 Helium Leak Detection: Spray Test on a Pumped Chamber (2D cross-section)

2D cross-section of a vacuum chamber being pumped while helium is sprayed on a suspected leak. Set chamber volume, pump speed, leak and outgassing rates, detector lag and alarm level, and watch pressure, helium partial pressure and the spectrometer reading on log graphs. Same throughput model as the 3D page, with four in-page numerical checks.
