Investigation of ions emitted from a tin fuelled laser produced plasma source

In this work ions emitted from a laser produced plasma created from a solid tin target have been analyzed using a spherical sector energy analyzer (ESA). Employing time of fiight analysis, the ESA allows determination of ion energy and charge stage as a function of ion emission angle. Ions of charge Sn ⁺¹ - Sn⁺⁹ with energy to charge ratios of 0.22 - 3.2keV have been investigated over a range of emission angles from 20 - 80 degrees, relative to the target normal, for three distinct laser pulse energies.
