Abstract
A mass spectrometer ionization cell includes a micropoint type cold cathode which emits electrons, an amagnetic material anode forming an ionization cage positively biased relative to the cathode and including an entry slot for emitted electrons facing the cathode, and an ion collector electrode which is held at a potential lower than that of the cathode. The electrode is disposed laterally of and outside the space between the cathode and the anode and extends from the cathode to the anode. An axial magnetic field is generated in the cathode-anode direction.
