Device for generating a dielectric barrier discharge and method for treating an object to be activated

A method of treating an object to be activated with a non-thermal atmospheric pressure plasma, comprising:

• removing a dielectric working chamber from a sterile package, the dielectric working chamber having a wall made of a dielectric material that encloses a working space, the wall having an outer side facing away from the working space, the outer side having metallization that is a metal layer applied to the wall in a material-bonding manner;
• inserting the dielectric working chamber into an opening of a base unit, the base unit having a high-voltage source;
• introducing the object to be activated into the working space;
• and
• applying a high voltage to the object to be activated or to the metallization so as to generate a dielectric plasma discharge between the object and the metallization.

A device for generating a dielectric barrier discharge for the treatment of an object to be activated with non-thermal atmospheric pressure plasma, comprising:

• a dielectric working chamber having a wall made of a dielectric material and enclosing a working space, the wall having an outer side facing away from the working space, the outer side having metallization that is a metal layer applied to the wall in a material-bonding manner, the working space being an open volume;
• and
• a high-voltage source which is configured to apply a high voltage to the metallization or to the object to be activated when the object to be activated is arranged in the working space,
• wherein the open volume is a non-closed volume such that ambient air from around the device is permitted to enter the open volume.
