AN ADAPTER SHAPING ELECTROMAGNETIC FIELD, WHICH HEATS TOROIDAL PLASMA DISCHARGE AT MICROWAVE FREQUENCY

摘要

The invention pertains to an adapter shaping electromagnetic field, which heats toroidal plasma discharge. It is intended for use in plasma torches dedicated for excitation/ionization sources in spectrometers. The adapter consists of at least two electromagnetic field shaping elements (1), which are stretched between the bushing (2) of the upper microwave connection and the bushing (3) of the lower microwave connection, wherein an element shaping electromagnetic field (1) is positioned to the surface pitch of the bushings (2, 3) at an angle ranging from 0 to 90 degrees.
