【 摘 要 】

We have performed a test run for laser cooling experiments with12C3+ion beams at an energy of 122 MeV/u at the CSRe with a pulsed laser. During this beamtime a lot of progress have been made. This was the first time we could successfully separate the12C3+ions and16O4+ions in the Schottky spectrum with the help of electron cooling. And our newly installed CPM detector worked well during the experiment. We tried to see effects from the interaction of the pulsed laser light with the stored12C3+ion beams, but no cooling effects could yet be observed.
