Local Ion Direction of Motion and Electron Flow in a Magnetically Insulated Diode
Abstract
Ion motion in a magnetically insulated diode was studied locally and simultaneously with the observation of the local electron flux to the anode. Sudden, brief ion deflections accompanied by intense electron bursts to the anode, were observed, evidently resulting from transverse electric fields in the diode gap. Slowly rising deflections of two classes were also found. The data suggest that they were caused by electric fields resulting from a changing shape of the anode plasma surface due to plasma depletion for the other. The shapes of the perturbations in the potential surfaces for both classes were deduced. The relation of each perturbation to the change in the electron flux to the anode may be explained qualitatively by considering the motion of a single particle. The size of the potential perturbations was shown to be a few centimeters and magnitude of the transverse electric fields was inferred to be up to 0.3 of the diode accelerating field. (jhd)
