Line overlap measurements for resonant photo-pumping of x-ray lasers

Conference ·
OSTI ID:7178974
Measurements taken on the LLNL EBIT to search for the possible photo- pumping of the 3p-3s lasing transitions in Ne-like ions of elements with Z=30-40 and the 4d-4p lasing transitions in Ni-like ions of elements with Z=47-73 are reported. A high-resolution crystal spectrometer was used to measure wavelengths of the Ne-like 2p-4d and the Ni-like 3d-5f and 3d-6f laser level feeding transitions relative to candidate pump lines in various H-, He-, and Ni-like ions. To date, the most promising candidate is Ni-like Pt pumping Ne-like Rb at 2512 eV. The line energies differ by 0.4[plus minus]0.1 eV or by 160 ppm.
