Experimentally investigated electron acceleration from submicron size Ar clusters-gas target irradiated by a 100 fs, 10 TW laser pulse having a high-contrast. Electron beams are observed in the longitudinal and transverse directions to the laser propagation. The measured energy of the longitudinal electron reaches 0.6 GeV and the charge of the electron beam in the transverse direction is more than 3 nC. A two-dimensional particle-in-cell simulation of the interaction has been performed and it shows an enhancement of electron charge by using the cluster-gas target.
