ANOMALOUS NOISE PEAK IN ADLER TUBES

Abstract

An experimental investigation of the noise stripping mechanism in two Adler tubes with high residual gas pressure (>0.000001 mm Hg) has revealed the presence of an anomalous noise peak (> 1 000 K). The peak occurs at a frequency somewhat lower than the cyclotron frequency. It is proposed that the peak is produced by elastically scattered beam electrons traveling slowly through the input coupler. The phenomenon is described in terms of an idealized theory which is in good agreement with the experimental findings.
