Recent results of a plasma Beat-Wave acceleration experiment are presented. A plasma wave is created in a D{sub 2} plasma by the beating of a Nd-YAG and a Nd-YLF laser pulse. Electrons at energies of 3 MeV are injected into the plasma. Several hundred electrons accelerated up to 3.7 MeV are observed in correlation with a Thomson scattering signal. The dependence of the electron acceleration on the plasma density demonstrates the beat-wave origin of the acceleration mechanism. This paper is mainly devoted to the description of the experimental set-up. A particular attention was paid to efficient electron injection and to background noise suppression. A preliminary analysis of the results is also presented. {copyright} 1995 {ital American Institute of Physics}.
