Identification of extreme-ultraviolet transitions in highly charged Zr and Mo ions
POSTER
Abstract
Spectroscopic measurements of highly charged highly charged Zr and Mo ions
were performed with the electron beam ion trap (EBIT) at the National Institute of
Standards and Technology and recorded with a flat-field grazing-incidence extreme-
ultraviolet spectrometer. A detailed collisional-radiative modeling was used to
identify and analyze the spectral lines in the wavelength range of 2 nm to 18 nm.
The electron beam energy was systematically varied between 4.5 keV and 12.5 keV
to selectively create different ionization stages. Reasonable agreement between the
measured spectra and the modeled spectra obtained by simulation of the non-
Maxwellian EBIT plasma was found, assisting the identification of many new lines
from Li-like to Ne-like ions. These lines arise from dominant electric as well as
magnetic-dipole transitions.
