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. 000357838 536__ $$0G:(DE-HGF)POF4-899$$a899 - ohne Topic (POF4-899)$$cPOF4-899$$fPOF IV$$x0 000357838 588__ $$aDataset connected to DataCite 000357838 650_7 $$2Other$$aAccelerator Physics 000357838 650_7 $$2Other$$aMC5: Beam Dynamics and EM Fields 000357838 693__ $$0EXP:(DE-Ds200)no_experiment-20200803$$1EXP:(DE-Ds200)theory-20200803$$5EXP:(DE-Ds200)no_experiment-20200803$$atheory$$eno experiment theory work (theory)$$x0 000357838 7001_ $$aBussmann, Michael$$b1 000357838 7001_ $$aGumm, Jens$$b2 000357838 7001_ $$aHannen, Volker$$b3 000357838 7001_ $$0P:(DE-Ds200)OR0680$$aKühl, Thomas$$b4$$ugsi 000357838 7001_ $$aLangfeld, Benedikt$$b5 000357838 7001_ $$aMa, Xinwen$$b6 000357838 7001_ $$aSchramm, Ulrich$$b7 000357838 7001_ $$aSiebold, Mathias$$b8 000357838 7001_ $$0P:(DE-Ds200)OR1222$$aSpiller, Peter$$b9$$ugsi 000357838 7001_ $$0P:(DE-Ds200)OR1264$$aStöhlker, Thomas$$b10$$ugsi 000357838 7001_ $$aUeberholz, Ken$$b11 000357838 7001_ $$aWalther, Thomas$$b12 000357838 7001_ $$aWen, Weiqiang$$b13 000357838 7001_ $$0P:(DE-Ds200)OR1685$$aWinters, Danyal$$b14$$ugsi 000357838 7001_ $$00000-0001-9787-8917$$aZimmermann, Frank$$b15$$eEditor 000357838 7001_ $$00000-0003-1848-2338$$aTanaka, Hitoshi$$b16$$eEditor 000357838 7001_ $$aSudmuang, Porntip$$b17$$eEditor 000357838 7001_ $$aKlysubun, Prapong$$b18$$eEditor 000357838 7001_ $$aSunwong, Prapaiwan$$b19$$eEditor 000357838 7001_ $$aChanwattana, Thakonwat$$b20$$eEditor 000357838 7001_ $$aPetit-Jean-Genaz, Christine$$b21$$eEditor 000357838 7001_ $$aSchaa, Volker R.
