We have achieved ion generations of several tens MeV in the laser driven ion acceleration using cluster-gas targets. The detailed knowledge of the initial target parameters is the key to understanding the acceleration mechanism. In present study, we have evaluated the sizes of CO$$_2$$ clusters, which formed in the supersonic expansion of CO$$_2$$/He and CO$$_2$$/H$$_2$$ mixed-gases, by measuring angular distributions of Mie scattered light from the clusters. The gas density profiles of the targets were also evaluated with an interferometry. Moreover, we have observed the energy spectra of generating electrons from the target irradiated by the J-KAREN laser in real time since the spectra can be a guide for searching the optimal condition of the ion acceleration. As a result, we found that the spectra vary significantly depending on the focal positions inside the target. We consider the correlation between the target initial condition and the electron energy spectra.
