Output and efficiency of the split-anode magnetron oscillating in the dynatron regime

An account is given of the performance of the split-anode magnetron when working at frequencies such that transit time can be neglected. An accurate and convenient method is described of determining this performance from the measurement of valve resistance at power frequencies. A series of results for one valve are included; these show the general influence of the various operating conditions. The anode modulation and frequency stability of the valve are discussed, while some measurements at radio frequency are given and the agreement of the two methods is found to be good.
