Abstract
A plasma-treatment instrument for treating a surface with a dielectric-barrier plasma field generated between an electrode and the surface has a high a.c. voltage supplied to the electrode by a controller. The electrode forms with a dielectric surrounding the electrode a cylindrical roller that is rotatably supported in a grip housing. The plasma-treatment instrument has a shell surface and is capable of being rolled along the surface. The plasma-treatment allows an efficient and safe treatment of the surface by virtue of the fact that the electrode includes at least two partial electrodes arranged alongside one another at equal intervals from the shell surface and which are insulated from one another by the dielectric. The at least two partial electrodes are connected to different terminals of a source of high a.c. voltage.
