Linear Optics Survey of the BESSY II Booster Synchrotron — •Paul Volz, Andreas Jankowiak, and Markus Ries — Helmholtz-Zentrum Berlin, Berlin

The proposed VSR upgrade for the BESSY II storage ring features photon pulses as short as 1.7 ps. The current injection system (linac, booster synchrotron, and transfer line) cannot provide electron bunches short enough to meet the required injection efficiency for TopUp operation. This contribution investigates if the momentum compaction factor of the booster synchrotron can be decreased just by changing the quadrupole strengths in the existing booster synchrotron lattice. It was found that by splitting the two quadrupole families into four the momentum compaction factor can be reduced.
