Bunched relativistic ion beams with a narrow momentum distribution are key for precision experiments at accelerator facilities. To reduce the relative momentum distribution, the principle of laser cooling can be utilized.
Past experiments conducted at the Experimental Storage Ring (ESR) at GSI have demonstrated the advantage of both cw and pulsed UV laser in decreasing the relative momentum distribution of bunched relativistic ion beams.
To achieve even better result, the integration of three laser systems, one cw and two pulsed laser, has been proposed for laser cooling at the FAIR SIS100. To implement this new scenario, overlap in space, time and energy of the three laser beams with the ion beam needs to be optimized.
This work presents the specifics of laser cooling with the integration of three laser systems and focuses mainly on creating good spatial overlap between ion and laser beams, also taking into account the need for active laser beam stabilization.
