Abstract
A particle simulation is used to test the hypothesis that the small, low phase velocity part of the antenna spectrum used in lower‐hybrid current drive experiments is important in bridging the gap between the velocity of the bulk of the electron distribution and the phase velocity of the major part of the spectrum. A simulation with the small, low phase velocity part of the spectrum numerically removed showed a strong quenching of the current compared to a simulation with the full spectrum, consistent with the hypothesis.Keywords
