Spectra of Multiply Charged Hydrogen and Nitrogen Ions in the Composition of Two and Multi-element Laser Plasma

Abstract The charge, energy, and spatial characteristics of multiply charged ions (hydrogen and nitrogen) of a two and multi-element laser plasma were studied using the laser ionization mass spectrometry method. The targets were made of pure C (i.e. graphite), Cu, polyethylene (CH2)n (consisting of hydrogen atoms (H) in a bound state), Cu[H] (with embedded H atoms) and Ti[H,N], Zr[H,N] (consisting of hydrogen atoms (H) and (N)) in the form of a thick cylinder with a thickness of l = 2 mm and a radius of R = 0.5 cm. It has been experimentally shown that the properties of both light and heavy ions in plasma depend both on the conditions for the entry of gas atoms into the target and on secondary processes occurring after the formation of a dense plasma on the surface of the sample. It has been found that the presence of light gas atoms significantly affects the parameters (for example, intensity and charge multiplicity) of heavier ions.
