Abstract : Measurements of discharge arc loss in helium as a function of gas pressure and transverse magnetic field are described. The discharge tube was incorporated in a cavity resonator and loss measurements were made by monitoring the cavity gain at resonance. Results indicate that for p sub o< or = 1 Torr, magnetic fields in excess of 600 gauss will produce 60-70% reductions in discharge arc loss. The power levels at which data were obtained are extrapolated to show that the results are valid for balanced ATR duplexing at 45 megawatts peak - 75 kilowatts average. Clean-up considerations based on the measured arc loss reductions indicate that by use of magnetic fields, the usable life of low pressure gas filled duplexers can be extended at least an order of magnitude beyond the present state-of-the-art. Progress is construction of an experimental model of a magnetic field duplexer is also described. (Author)
