	VEPP-2000 electron-positron collider has been completed in the Budker INP in 2007. First beam was captured in a special lattice with switched off final focus solenoids. This regime is used for all machine subsystems test and calibration as well as vacuum chamber treatment by synchrotron radiation with electron beam current up to 150 mA. Another special low-beta lattice with solenoids switched on partially was used for the first test of the round beam option at the energy of 508 MeV. Studies of the beam-beam interaction were done in "weak-strong" and "strong-strong" regimes. Measurements of beam sizes in the both cases have indicated beam behaviour similar to expectations for the round colliding beams. Also the first collider energy calibration at the phy-meson resonance was performed with SND detector. Since the end of 2009 VEPP-2000 started first experimental work with both particle detectors SND and CMD-3 at the energies of 500-950 MeV range with the lattice mode close to project.

TUCHX03	Crab Waist Approach: from DAΦNE to SuperB	emittance, sextupole, factory, collider	6
	M. Zobov INFN/LNF, Frascati (Roma)
	The crab waist collision scheme (CW) was proposed and successfully tested at the Phi-factory DAΦNE. At present this scheme is considered to be most attractive for the next generation lepton factories. In particular, the novel scheme is a key element of the SuperB project, a new SuperB-factory with a luminosity about two orders of magnitude higher than that achieved at the present B-factories (KEKB and PEPII). In this paper we summarize the results achieved at DAΦNE after implementation of the CW collision scheme and discuss the status of the SuperB project.

THCHA01	The Nonlinear Transformation of a Ions Beam in the Plasma Lens	plasma, ion, focusing, target	280

	The focusing capabilities of a plasma lens depend on the stage of plasma development. Under certain conditions a magnetic field is linear, that allow to focus the beam to a very small spot. In other conditions, the magnetic field is nonlinear, that allow formation of hollow and others beam structures. The work deals with the study of the last type of a plasma lens. Calculations and measurements were performed for a C+6 and Fe+26 beams of 200 MeV/a.u.m. energy. The obtained results and analysis are reported.
