Abstract
The invention relates to a quadrupole electrode arrangement comprising two shaped parts (10, 11). Each shaped part (10, 11) is produced from an insulating plate-shaped carrier (2) and a metal blank (1) fastened thereto. Each two of the four opposing electrode surfaces (4.1-4.4) are, for example, milled, turned and ground from the metal blank. Each shaped part (10, 11) also has a ground connection surface (6.1, 6.2) which defines the distance of the quadrupole electrode pairs precisely when the two structural parts are joined.
