Note: application of UF-4 emulsion films to detect low-energy ions from plasmas produced by laser ablation.
Detection of low-energy ions via Thomson parabola mass analyzer in the absence of any additional electrical systems is examined. Numerous low-energy ions were recorded on UF-4 solid state emulsion films. Kinetic energies between 1 and 4 keV of ions generated by YAG laser focused on Al and Ti targets were obtained using Thomson parabola measurements. Characteristics of ion tracks on the UF-4 detector are discussed in terms of pressure ranges of vacuum chamber. Moreover, differences in charges of ions between this study and previous spectroscopic measurements are discussed.
