The synchrotron radiation at SESAME is produced at electron energy 2.5GeV. The electron acceleration process takes place through three accelerators. The injector system (consists of a 20 MeV microtron and 800MeV booster synchrotron) fills the storage ring with electrons at 800MeV. The kinetic energy of the electrons is then ramped to a 2.5GeV in the storage ring that is used as a synchrotron during the daily refill phase. 

Electron beam keeps circulating in the storage ring that is maintained at a very low pressure (around 10-9 mbar) by the vacuum system. The electrons in the storage ring are guided by a set of bending and focusing magnets to ensure that they remain focused in a small cross section and close to their ideal orbital path. The beam behavior is monitored by the diagnostic system. The radiation emitted in dipole magnets or insertion devices is collected at the beamlines’ front-ends and then guided along the beamlines’ optical elements to the experiment. The energy released as a synchrotron radiation in each turn is restored to the electron beam by four radio frequency cavities. The electrical and radiation heat deposited into the storage ring, front-ends and beamlines’ components is cooled down by the cooling system.  All the mentioned operation process is managed by the control system.
