Abstract

There is provided an inductively coupled plasma reactor. The inductively coupled plasma reactor is connected to a transformer with multiple magnetic cores and a primary winding, to transfer an electromotive force for plasma discharge to a plasma discharge chamber of a reactor body. Parts of magnetic core positioned in side the plasma discharge chamber are protected by being entirely covered by a core protecting tube. The primary winding is electrically connected to a power supply source providing radio frequency power. In the inductively coupled plasma reactor, since a number of magnetic core cross sectional parts are positioned inside the plasma discharge chamber, the efficiency of transferring the inductively coupled energy to be connected with plasma is very high.
