The novel soft X-ray light source using the supersonic expansion of the mixed gas of He and CO, when irradiated by a femtosecond Ti:sapphire laser pulse, is observed to enhance the radiation of soft X-rays from the CO clusters. Using this soft X-ray emissions, nanostructure images of 100-nm thick Mo foils in a wide field of view (mm scale) with high spatial resolution (800 nm) are obtained with high dynamic range LiF crystal detectors. We also demonstrate the acceleration of charged particles via the laser-cluster interactions.
