Method and arrangement for generating an atmospheric pressure glow discharg plasma (apg)

摘要

Method and arrangement (1) for generating an atmospheric pressure glow plasma APG (7), where in a plurality of electrodes, (4, 5) are arranged defining a discharge space (10) for forming said plasma (7). The electrodes (4,5) are connected to a power supply (8) providing an AC-voltage having a frequency of at least 50 kHz to the electrodes (4,5). A gaseous substance (6) is provided in said discharge space and comprises t least one of a group of argon, nitrogen and air.
