The GSI Accelerator Facility
 |
GSI operates a unique heavy-ion accelerator system. At this accelerator,it is possible to not only prepare ion beams of all theelements, up to and including uranium — the heaviest naturallyoccurring element — in any state of electric charge, but also toaccelerate these beams to nearly the speed of light. The facilitycan also be used to create and accelerate beams of radioactivenuclei. |
UNILAC - Linear Accelerator
 |
UNILAC — a 120-meter long linear accelerator — accelerates theions to 20 percent of the speed of light.
|
SIS - Heavy Ion Synchrotron
 |
In the heavy ion synchrotron SIS with a circumference of 216 meters, the ion beam is further accelerated up to 90 percent of the speed of light in the course of several hundred thousand revolutions.
|
ESR - Experiment Storage Ring
 |
The previously accelerated ions — whether stable or radioactive — can be stored in the experimental storage ring ESR (circumference 216 meters). During this storage time, they complete several million to several billion revolutions at a constant, high speed.
