First results from the freiburg electron beam ion trap FreEBIT

In the first measurements at the Freiburg electron beam ion trap FreEBIT, h ighly charged ions of Xe, Ba,W, Kr and Ar have been observed (with charge s tates up to 63+) by means of X-ray spectroscopy Experiments with an optical imaging spectrograph have been also carried out. Forbidden transitions in the visible range have been measured, from Kr22+ and Xe32+ stored in the tr ap. The resolution achieved in the optical range is gamma/delta gamma appro ximate to 4000.
