The aim of electron ripple injection (ERI) is to create a radial electric field (E{sub r}) layer by external and non-intrusive means, using electron cyclotron resonance heating (ECH) and a localized magnetic ripple field. The ultimate goal is to use the generated E{sub r} layer as a tool for tokamak plasma transport modification. Motivated by semi-analytical analysis and numerical Monte-Carlo guiding-center simulation results [1], a series of experiments have been performed to elucidate the underlying key physics of the ERI concept. The experimental results are in reasonably good agreement with theoretical predictions. {copyright} {ital 1997 American Institute of Physics.}
