چکیده انگلیسی
The density of neutral oxygen atoms in the MESOX set-up, one device of the PROMES-CNRS solar facilities, was determined by a fiber-optics catalytic probe (FOCP). Plasma was created in a flowing air within a quartz tube with the outer diameter of 5Â cm by a 2.45Â GHz microwave generator with the output power up to 1000Â W. The flow of air was varied between 4 and 20Â l/h. The O-atom density was found to increase monotonously with the increasing discharge power, and it decreased with the increasing flow rate. The degree of dissociation of oxygen molecules in the plasma column depended largely on the flow rate. At the air flow of 4Â l/h it was about 80% but it decreased to about 20% at the flow of 20Â l/h.
