  • Hilleret, N. (1999). “Leak Detection”. In S. Turner (PDF). CERN Accelerator School, vacuum technology: proceedings: Scanticon Conference Centre, Snekersten, Denmark, 28 May – 3 June 1999. Geneva, Switzerland: CERN. pp. 203–212. http://doc.cern.ch/yellowrep/1999/99-05/p203.pdf. "At the origin of the helium leak detection method was the Manhattan Project and the unprecedented leak-tightness requirements needed by the uranium enrichment plants. The required sensitivity needed for the leak checking led to the choice of a mass spectrometer designed by Dr. A.O.C. Nier tuned on the helium mass."
