Abstract : A study has been made of the role of electron attaching gases in controlling the characteristics of a high power microwave duplexer discharge. The effects of dissociation-recombination phenomena in an oxygen discharge were investigated by observing recovery time-arc loss variations as a function of interpulse period. Arc loss measured at the end of the high power pulse was used as an indication of electron density at the start of the recovery period. Analysis of the data yield a value of 5 x 10 to the -6th power attachments/collision for thermal electrons in the recovery period following a duplexer discharge in oxygen. This compares with a value of less than 10 to the -7th power attachments/collision estimated by Takeda and Dougal from phase shift measurements during the recovery period of a water vapor duplexer discharge.
