In future ring-based light sources (DLSR), the combination of ultra low emittance, high current and narrow chambers will mean that collective effects will be important!
January 16-17 2014, SOLEIL , TWIICE 2014
Collective effects phenomena occurring in synchrotron radiation sources include:
Beam instabilitiesLifetime-limiting effectsIon effects
Strongly influence the quality of synchrotron radiation delivered to the users.
In view of the high costs in constructing a synchrotron radiation facility, a reduction of the beam quality due to collective effects is not acceptable.
Countermeasures have to be considered at an early stage of the machine design.
