41. 7 Cell principle Magnetic deflection spectrometry Leak flow rate Vacuum operation Separation of He ions from noise Total pressure A 30 Analyzer cell operating principle The mass spectrometry analyzer cell is used for helium partial pressure measurements The molecules of the gas being analyzed are bombarded by an electron beam from a heated tungsten filament 1 in an ionization chamber 3 A large proportion of the molecules are transformed into ions These ionized particles are accelerated by an electrical field the acceleration voltage A magnetic field deflects the ion beam by a radius propotional to the mass of the ions The acceleration voltage directs the Helium ions to the target at the entrance of an amplifier an electron multiplier based system developed and patented by ALCATEL The stream of Helium ions is proportional to the partial pressure of helium in the installation and its measurement is used to find the value of the flow rate of the detected leak lt is essential for the total pressure in the analyzer cell to be less than 104 mbar so that the paths of the electrons and ions are not disturbed by residual molecules In order to separate the helium ions from the noise due to dispersed ions a braking electrode 6 placed in front of the target eliminates secondary low energy ions The top of the cell contains an auxiliary electrode which collects ions that have a higher mass than that
