    摘要： The invention relates to a method for cooling a plasma processing system for processing a mixture of particularly gaseous fluids, which comprises a means for coupling a source of microwave power to a mixture of particularly gaseous fluids flowing in a dielectric tube at the level of the coupling means adapted for transferring a portion of the microwave energy to the fluid mixture in order to generate therein a plasma for initiating the breaking of at least some chemical bonds of the fluid molecules, wherein said dielectric tube is at least partially cooled down by a coolant flow in thermal contact with the outer wall of the tube to be cooled. According to the invention, on the one hand, the coolant flow in thermal contact with the dielectric tube flows in a direction opposite to that of the fluid or fluid mixture in the dielectric tube and, on the other hand, the coolant includes at least one oil selected from linear alpha-polyolefins having a carbonated chain of at least ten carbon atoms and/or perfluorocarbonated liquids having a dielectric constant ∈ lower than 2.5, a microwave absorbance tan δ of between 10−2 and 10−4, and a specific heat Cp
