DESCRIPTION:Speakers: Danyal Winters (GSI Helmholtzzentrum für Schwerione
 nforschung GmbH(GSI))\n\nRecent storage ring experiments have demonstrated
  the power and the potential of laser cooling of bunched relativistic ion
  beams. Encouraged by this\, the heavy-ion synchrotron SIS100 at FAIR (Da
 rmstadt\, Germany) will be equipped with a truly unique laser cooling faci
 lity. A sophisticated combination of 3 newly developed UV (257 nm) laser 
 systems and modest rf-bunching will allow for fast cooling of injected in
 tense heavy-ion beams. There will be two powerful pulsed laser systems wi
 th MHz repetition rates and variable pulse duration (10-100 ps and 50-740 
 ps) and one powerful tunable cw laser system. The picosecond laser pulses
  are broad in frequency and will enable fast cooling of injected ion beam
 s with a large initial longitudinal momentum spread. The cw laser can be 
 quickly tuned over a large range and has high spectral power\, forcing the
  ion beams to remain cold during storage. This combination of 3 UV laser 
 beams should be up for the challenge of suppressing intra-beam scattering
  and space charge effects. \nI will present an overview and the status of 
 the SIS100 laser cooling facility and will also show results from laser c
 ooling experiments at the ESR storage ring of GSI. \n\nhttps://indico.gsi.
