	A.E. Aksentyev, A.A. Melnikov, V. Senichev RAS/INR, Moscow, Russia A.E. Aksentyev MEPhI, Moscow, Russia V. Ladygin JINR, Dubna, Moscow Region, Russia
	A method for manipulating the orientation of the beam polarization axis based on using the so-called "spin-navigator" technique in a storage ring operating in the spin-transparent regime has been modelled. The beam particles’ spin- and orbital dynamics have been numerically investigated with the purpose of determining the method’s feasibility; the latter’s effect on spin-decoherence has been studied also.

	The robustness of spin-navigator based method for manipulating the beam polarization axis has been investigated with respect to bend magnet installation errors. Toward that end, variation of the invariant spin axis components along the beamline of an imperfect storage ring operating in the spin-transparent mode has been estimated. The beam polarization vector behavior in the given lattice has been investigated. Conclusions are made regarding the feasibility of using spin navigator solenoids for defining the beam polarization axis in the detector region.

	The 4th generation light source, the Ultimate Source of Synchrotron Radiation (USSR) is under design, to be built in Moscow region (Russia). It will be a 6 GeV and about 1100 m circumference storage ring synchrotron. Baseline lattice of the USSR for now is a scaled version of the ESRF-EBS Hybrid Multi-Bend Achromat (HMBA) lattice that was successfully commissioned in 2020. Its natural horizontal electron beam emittance is about 70 pm·rad. Further reduction of beam emittance can be achieved with the use of reverse bending magnets. The evolution of the envisaged lattices for the USSR storage ring, including options with reverse bends will be presented.

	Funding: The reported study was partially funded by RFBR, project number 19-29-12039 Nowadays the upgrade project of the 2nd generation synchrotron radiation source operating at NRC Kurchatov Institute has been ongoing. The main aim of the project is to create a new synchrotron radiation source with the same 124 m circumference and providing synchrotron radiation properties inherent to the 3rd generation sources (emittance ~ 3 nm·rad). The new machine will consist of new storage ring with 2.5 GeV electron energy, full energy booster synchrotron and 0.2 GeV linac. The mandatory requirement for the project is to keep all currently operating beamlines. In this article we present the design challenges and approaches for this machine, the conceptional design and baseline lattice.

WED04	Precise Analysis of Beam Optics at the VEPP-4M by Turn-by-Turn Betatron Phase Advance Measurement	optics, collider, betatron, experiment	79
	I.A. Morozov, P.A. Piminov, I.S. Yakimov BINP SB RAS, Novosibirsk, Russia
	Turn-by-turn (TbT) beam centroid signals can be used to evaluate various relevant accelerator parameters including betatron frequencies and optical functions. Accurate estimation of parameters and corresponding variances are important to drive accelerator lattice correction. Signals acquired from beam position monitors (BPMs) are limited by beam decoherence and BPM resolution. Therefore, it is important to obtain accurate estimations from available data. Several methods based on harmonic analysis of TbT data are compared and applied to the VEPP-4M experimental signals. The accuracy of betatron frequency, amplitude, and phase measurements are investigated. Optical functions obtained from amplitudes and phases are compared.
