Abstract
It is shown that the placement of a minimum-B type magnet assembly near the anode of a discharge tube is effective in suppressing discharge noise. Observations using an oscilloscope and a spectrum analyzer indicate that the noise amplitude can be decreased by 20 to 40 dB. The electron energy distribution curve, which is distorted by noise, becomes smooth and reliable after the suppression. The merit of the method is that no electric contact is necessary.Keywords
