Abstract The following progress report presents some of the X-ray measurements performed during the last year on the Livermore SuperEBIT facility. The measurements include: direct observation of the spontaneous emission of the hyperfine transition in ground state hydrogenlike holmium, 165Ho66+; measurements of the n=2 → 2 transition energies in neonlike thorium, Th80+, through lithiumlike thorium, Th87+, testing the predictions of quantum electrodynamical contributions in high-Z ions down to the 0.4% level; measurements of the isotope shift of the n=2 → 2 transition energies between lithiumlike through carbonlike uranium, 233U89+⋯ 86+ and 238U89+⋯ 86+, inferring the variation of the mean-square nuclear charge radius; and high-resolution measurements of the Kα radiation of heliumlike xenon, Xe52+, using a transmission-type crystal spectrometer, resolving for the first time the 1s2p3P1 → 1s21S0 and 1s2s3S1 → 1s21S0 transitions individually.
