The Low-α Lattice and Bunch Length Limits at BESSYVSR — •Paul Goslawski, Markus Ries, Martin Ruprecht, and Gode Wüstefeld — Helmholtz-Zentrum Berlin, D-12489 Berlin, Germany

An upgrade of the BESSY II ring to a Variable bunch length Storage Ring (BESSYVSR) has been recently proposed [1], by introducing strongly focusing superconducting cavities. This will allow to store simultaneously long and short bunches. In the regular user optics, bunch lengths of 15 ps (rms) and down to 1.5 ps (rms) are expected. Bunches as short as 300 fs (rms), close to the bunch length limit, and a ring current of 3.5 mA at the bunch bursting threshold can be provided by using a modified low-α optics. This presentation will discuss the properties of the low-α optics and intrinsic bunch length limits, given by coupling effects of the longitudinal and horizontal plane.
