Abstract
A device (1) for amplifying the current of an abnormal electrical discharge, characterized in that it comprises an electrode which is positively polarized (2) and associated with a magnetic circuit (3) producing a magnetic field (4) which is uniformly divergent, whereby the intensity on the surface of the electrode is more than approximately 6.102 Tesla, the electrode being positioned in the region where the magnetic field is at its most intense.
Claims24
A device (1) for amplifying the current of an abnormal electrical discharge,
- wherein the device is arranged to amplify the current of the abnormal electrical discharge at a substrate being treated and includes an electrode disk (2) which is positively polarized and associated with a magnetic circuit (3) producing a magnetic field (4) which is uniformly divergent, whereby the intensity on the surface of said electrode is more than approximately 6.10−2 Tesla, said electrode being positioned in the region where the magnetic field is most intense.
