An absolute measurement of the Is Lamb shift in hydrogenlike chromium has been made to a precision of 0.7%, using an EBIT and a curved crystal spectrometer in the Johann geometry. The measured value of the Lamb shift is 3.030(15) eV. This represents the most precise Is Lamb shift measurement ever made on a highly charged ion. The measurement utilized the Lyman 0:1,2 transitions using manganese and chromium J(0: and J({3 as calibration lines. A measurement was also made of the difference in the Is Lamb shift of chromium and titanium to a precision of 6%, yielding a difference of 0.779(41)eV. This was made by measuring the Lymano: and Balmer {3 difference of hydrogenlike chromium and titanium, respectively, a large portion of which is due to QED. A new injection technique has been developed where neutral atoms formed as a result of laser ablation are injected in to the EBIT. This technique is shown to be comparable with l\UVOC injection in terms of the number of hydrogenlike vanadium ions formed in the EBIT. Laser ablation injection has also been demonstrated with tin, lead and stainless steel also being successfully injected and trapped in the EBIT.
