Radioactive tracer study of gas cleanup in duplexer discharges

Radioactive tracer gases are used to study the RF-activated gas cleanup process in duplexer discharges. The radioactive mapping technique provides means of calculating the effective discharge area and expected operating life of quartz tubes used in pre-TR and ATR devices. In metallic-wall TR tubes, the tracer technique is also useful for the study of dominant sorption mechanisms and the critical area of discharge.
