	VEPP-2000 e⁺e⁻ collider at Budker Institute of Nuclear Physics was commissioned in 2009 and collected data during three runs in whole designed energy range of 160-1000 MeV per beam. The Round Colliding Beams concept was implemented at VEPP-2000 to get a significant enhancement in beam-beam limit. The beam-beam parameter value as high as 0.12 per IP was achieved at intermediate energy. To obtain more intensive beams and achieve target luminosity at top energies the injection chain upgrade was done during 2013-2016. Presently VEPP-2000 is recommissioned and ready to start data taking.

	The Future Circular Collider-ee aims to get high luminosity which mainly relies upon high charge and low geometric emittance in the collider. The FCC-ee is a future project of CERN to operate as Z, W, H and tt factories with varying energies between 45.6 to 175 GeV. Among those, the total charge requirement is peaked for Z-operation (i.e. 91500 bunches of electron and positron with 3.3·10¹⁰ particles per bunch) meanwhile this mode targets the smallest geometric emittance in the Collider. To reach the goal, the normal conducting S-band Linac has been designed to accelerate 4·10¹⁰ particles in a bunch to 6 GeV and send two bunches per RF pulse within a repetition of 100 Hz. The FCC-ee positrons will also be created inside the linac at 4.46 GeV and accelerated to 1.54 GeV. These positrons are damped at the designed Damping Ring at that energy, and then transferred back to the Linac to meet the same characteristics of electrons. Therefore, in this paper, we'd like to discuss the transmission and robustness of the Linac and the dynamic aperture of the Damping Ring which has to be large enough to accept the incoming beam and cover the probable shrink due to the misalignments.

The Future Circular Collider-ee aims to get high luminosity which mainly relies upon high charge and low geometric emittance in the collider. The FCC-ee is a future project of CERN to operate as Z, W, H and tt factories with varying energies between 45.6 to 175 GeV.
