Abstract :
Alladin II is a lattice variation of the Alladin 1 GeV electron storage ring located at the Synchrotron Radiation Center. The new lattice is realized without any physical repositioning of dipoles or quadrupoles by uncoupling and separately powering four sets of quadrupoles. The Alladin II lattice is characterized by long straight sections having zero dispersion and symmetric beta functions that can be varied from 0.5 to 5 m. The Aladdin and Aladdin II lattice functions are compared and dynamic aperture calculations for each lattice are presented. Even though the dynamic aperture for Alladin II is reduced slightly, it is still dominated by the physical aperture. Changes in injection and in the characteristics of the dipole synchrotron radiation sources are also discussed.<>
