Intermittent enhancement of local electron flux has recently been observed in a linear electron cyclotron resonance plasma. The aim of this paper is to measure the 2-D distribution of the electron flux, which appears at random positions in the plasma cross section, using intensified charge-coupled device imaging. A series of images of the emission from the Ne 2p 1 state is presented; it clearly demonstrates a circular region of enhanced excitation due to increase in the electron temperature.
