6 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 , SOLEIL, TWIICE 2014 Collective effects phenomena occurring in synchrotron radiation sources include: Beam instabilities Lifetime-limiting effects Ion 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.
