A mass spectrometer and mass analyzer, which has a pulse generator

摘要

Mass analyzer (102), which has the following features:a pair of planar electrode structures (202, 205), the annular electrodes (202), concentrically around an axis (206) are arranged and for generating an annular ions reflecting mirror region are configured and electrodes (203, 205) for generating an annular ions focusing lenses region (215), the of the annular mirror region is surrounded, are configured, whereby the electrode structures (202, 205) of the pair of diametrically opposite to one another, parallel to one another and in the direction of the axis (206) are arranged axially spaced apart from one another, whereby an electrode (205) of the pair of planar electrode structures (202, 205) has an opening (207); andan ion mirror (212), which in a space between the pair of planar electrode structures (202, 205) is arranged, wherein the ions mirror (212) is configured to ions through the opening (207) for receiving and of the lenses region (215) and to reflect.
