Cascade emission in electron beam ion trap plasma of W ion
Spectra of the W ion are studied using the collisional-radiative
model (CRM) with an ensuing cascade emission. It is determined that the cascade
emission boosts intensities only of a few lines in the nm range. The
cascade emission is responsible for the disappearance of structure of lines at
about 6 nm in the electron beam ion trap plasma. Emission band at 4.5 to 5.3 nm
is also affected by the cascade emission. The strongest lines in the CRM
spectrum correspond to transitions, while
transitions arise after the cascade emission is
taken into account.Comment: 16 pages including 4 figures and 3 table
