The course of experiments described in this book are focused to provide insight into the production of atomic, molecular and mixed clusters from solid and gas, investigation of difference in the ionization mechanisms of clusters subjected to high intensity laser pulses. Carbon cluster sources based on sputtering and laser ablation are developed to generate a beam of clusters. The formation of carbon clusters in the sooting environment is confirmed using optical emission spectroscopy. Clusters heavier than dimer are detected by a linear time-of-flight (ToF) mass spectrometer. Neutral clusters...
