  The DBA optics lattice of Elettra, the third generation Italian light source is closer to DBA minimum emittance condition than any other similar lattice. At the same time, although the lattice is also optimized for large acceptance, it is very inflexible to any changes like the reduction of the momentum compaction (very desirable to the IR and SR-FEL beam lines). Nevertheless a solution has been found and consists in abandoning the achromat condition and reversing the polarity of some quadrupole and sextupole families. This special optics and its applications to Elettra are presented and discussed.

  Since May 2010 Elettra, the third generation Italian light source, operates regularly for users at both 2 and 2.4 GeV in top-up. In this paper the experience during more than a year of operation in top-up at both user energies is discussed and the machine up time statistics presented and compared with the before top up period.
