The helium from the test job leak travels through to system, its partial pressure is measured and results are displayed on the measurement meter. The HMSLD operating principle consists of ionizing gases in a vacuum and accelerating various ions through an electric and magnetic field. The helium ions are separated and collected and the resulting ion current is amplified and measured as a leak in m.bar litssec.
