EUV spectra of Rb-like to Ni-like dysprosium ions in an electron beam ion trap



Deirdre Kilbane, G. O'Sullivan, Yuri A. Podpaly, John D. Gillaspy, Joseph Reader, Yuri Ralchenko


Extreme ultraviolet radiation emitted from highly-charged dysprosium ions was measured at the National Institute of Standards and Technology. The ions were created, trapped, and excited in an electron beam ion trap (EBIT), and the spectra were recorded with a flat-field grazing-incidence spectrometer in the wavelength range 3nm to 17nm. Tuning the electron beam energies between 1.2 keV and 2.0keV resulted in a selection of Rb-like Dy$^29+}$ to Ni-like Dy$^38+}$ ions. Identification of strong n=4-n=4 transitions was achieved by collisional-radiative modeling of the EBIT plasma. A total of 64 spectral lines were recorded, including 54 new identifications.
