Various aspects of the magnetically self-pinched electron flow patterns in megavolt megampere diodes have been investigated. The onset of pinching has been correlated with a transition from Child-Langmuir to parapotential voltage-current characteristics. The average velocity at which the pinch sweeps towards the axis has been measured and is found to be approx.2 mm/nsec. The invariance of the current under geometrical scaling is demonstrated, and the connection between this invariance and plasma motion is discussed. Measurements of total diode current are compared with existing theories and agreement is found with the parapotential model. (AIP)
