Abstract : A study has been made of the role of electron attaching gases in controlling the recovery time characteristics of TR tubes. Recovery time measurements have been made for discharges in a quartz cylinder TR input window. The effects of chlorine, bromine, hydrogen, and oxygen were investigated over a 5 to 20 Torr range. Extremely short recovery times of 0.05 to 0.25 microseconds, have been observed for bromine and chlorine discharges at 400 to 2000 w peak power and 0.1 duty cycle in X-band. Analysis of curves of attenuation versus time has yielded values of electron attachment frequency. The analysis is based on variations of discharge conductivity and electron density with time. The measured attachment frequencies are compared with values obtained by other techniques and criteria are discussed for applying electron attachment data to predicting recovery time behavior.
