Abstract:
A new method is presented to dissociate iodine molecules in gas discharge. A high repetition rate spark gap is designed and used to trigger the circuit. Absorption spectroscopy is applied to measure the dissociation fraction of iodine molecules. It is found that more than 35% of iodine molecules are dissociated. The effect of switching frequency on the dissociation coefficient is investigated by changing the frequency of the rotating spark gap. Pulsed and equivalent direct current circuits are compared, and it is found that in the constant current glow discharge the dissociation fraction is near to the zero and negligible.
