ABSTRACT:
A method of making an ion filter having an electrically insulating body formed of at least two longitudinal parts and having metallized inner faces of generally hyperbolic cross-sectional shape, comprises the following steps:
(a) making longitudinal body segments constituting the longitudinal parts;
(b) grinding the longitudinal body segments to the predetermined cross-sectional shape;
(c) metallizing those ground surface portions of each longitudinal body segment that are to serve in the ion filter as inner electrode faces for generating electric fields of predetermined configuration; and
(d) securing, subsequent to the metallizing step, the longitudinal body segments to one another.
