AB  - We present new (preliminary) results from a recent (May 2021) beam experiment for laser cooling of bunched relativistic carbon ion beams at the ESR of the GSI Helmholtz Centre in Darmstadt, Germany. We were able to use the new pulsed UV laser system from the TU Darmstadt, which has a very high repetition rate, a variable pulse duration and high UV power (up to 250 mW @ 257 nm). Using this laser, we have - for the first time - demonstrated laser cooling of bunched relativistic ion beams for different laser pulse durations (166-740 ps) at a  10 MHz repetition rate. In addition, we could use the moveable in-vacuo (X)UV detection system from Münster University to study the fluorescence from the laser-excited ions. Finally, we have observed clear effects in the amount of detected fluorescence from the ions using our new ion bunch - laser pulse timing scheme. These studies are also highly relevant for the SIS100 laser cooling pilot facility, which is currently being realized at FAIR.
