Device for directly monitoring plasma jet i.e. cold plasma jet, has measuring amplifier connected with output unit such that measuring signal is displayed by output unit, where measuring signal allows direct inference on produced plasma jet

摘要

The device has a current collector (9) provided in a plasma jet for transferring electrical current. An end of the current collector is electrically and conductively connected with a grounded housing (1) of a plasma generator. A matching resistor (8), a current measuring device (6) and a measuring amplifier (7) are connected between ends of the current collector. The measuring amplifier is connected with an output unit (11) such that measuring signal is displayed by the output unit, where the measuring signal allows direct inference on the produced plasma jet. An independent claim is also included for a method for directly monitoring a plasma jet.
