Storage Ring ESR

The experimental storage ring ESR has a circumference of 108 meters. Ions accelerated before by the linear accelerator UNILAC and the ring accelerator SIS18 can circulate in the ESR at high speeds performing several millions of circulations per second. They are stored and used for experiments. Cooling systems allow high precision experiments. By using the fragment separator FRS also new particles like new isotopes can be stored and measured in the ESR.
