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.
