Influence of molecular oxygen on iodine atoms production in an RF discharge

Abstract

The results of the experiments and modeling of CH 3 I dissociation in a 40 MHz RF discharge plasma are presented. A discharge chamber of an original design, consisting of quartz tubes between two planar electrodes, permitted us to produce iodine atoms with a number density up to 2 × 10 16 cm −3 . In this discharge chamber, contrary to the previous experiments with a DC discharge and RF discharge with bare planar electrodes, contamination of the walls of the tubes did not disturb discharge stability, thus increasing iodine production rate.

Ozone and oxygen atoms production in a dielectric barrier discharge in pure oxygen and O2/CH4 mixtures. Modeling and experiment

“…The most common application of a DBD is ozone production [17,18]. DBD was also studied for plasma assisted combustion [19], and a radio frequency DBD-even for singlet oxygen [20] and iodine atoms [21] production for oxygeniodine laser.…”
