WEOAA01	Transverse Emittance Exchange for Improved Injection Efficiency	2028
	P. Kuske, F. Kramer HZB, Berlin, Germany
	In most cases beam is injected into electron storage rings in the horizontal plane and off-axis. The larger the horizontal emittance of the injected beam the larger the acceptance of the ring has to be. The injected beam is usually delivered by a synchrotron. In case the vertical acceptance of the ring is sufficiently large one can take advantage of the small vertical emittance reached in well aligned and tuned synchrotrons since the transverse emit-tances can be exchanged with the help of skew quadru-pole magnets. A few possible processes will be discussed: emittance exchange with static magnets in the transfer line between synchrotron and ring or emittance exchange in the synchrotron shortly before extraction with time dependent magnets. This could be a suddenly switched-on normal or skew quadrupole magnet or skew quadru-pole fields oscillating at a frequency fulfilling the reso-nance condition. Estimates for these magnets and their design will be given.

The BESSY II injector system consists of a 50 MeV Linac, installed in preparation for TopUp operation, and a 10 Hz fast-ramping booster synchrotron. The system provides injection efficiencies into the BESSY II storage ring well above 90 % . This contribution reports on the present status, measurements of energy acceptance and other essential beam parameters as well as studies on coupled-bunch-by-bunch instability. Requirements for BESSY-VSR and possible upgrade scenarios are discussed.
