Abstract :
Experimental studies were performed, to measure the nonlinear behavior of the momentum compaction factor α at the BESSY II electron storage ring. Based on these results the momentum acceptance of the storage ring can be derived. Several sets of measurements at different values of the horizontal chromaticity in the range of ΔQ x/(Δp/p0)=ξx=-5.5...+8.1 were generated. Depending on tune and horizontal chromaticity particles in the range from -4%<Δp/p0<8% could be stored
