High frequency (hf) plasma, which is now frequently used both in research and practical application, especially in plasmachemistry, has been generated in different gases almost at reduced pressure. Discharges burning in flowing gases at atmospheric press ure are less known and used. Recently, a completely new type of hf unipolar/bipolar discharge burning from a hollow electrode at atmospheric pressure in a working gas flowing through the electrode with input hf power up to 500 W and a plasmachemical devi ce for generation of such discharge, called plasma pencil, was developed at the Department (patent No. PV 1476-98 CZ). First results show that the discharge with similar properties can be generated at atmospheric pressure not only by hf generators by als o by means of dc, low frequency and microwave sources. Moreover, it was found that the plasma pencil can also work in liquid solution, which can be used for modification of surfaces (cleaning from corrosion, ablation, etching, deposition of thin films, e
