	The most effective way to increase the brilliance of synchrotron light sources is the reduction of beam emittance. To improve the CANDLE synchrotron light source performance, a new low emittance facility has been designed with the account of the new developments in magnets fabrication technology of last decade. The lattices for the booster and storage rings are re-designed keeping the geometrical layout of the facilities. The new design provides the beam emittance in storage ring below 5nm with sufficient dynamic aperture. This report presents the main design considerations, the linear and non-linear beam dynamics aspects of the modified facility performance.

TUPRI040	New BBA Algorithm for Electron Beam Orbit Steering in Linear Accelerators	1650
	A. Sargsyan, V. Sahakyan, G.S. Zanyan CANDLE SRI, Yerevan, Armenia W. Decking DESY, Hamburg, Germany
	In linear accelerators or transfer lines beam-based alignment (BBA) techniques are important tools for beam orbit steering. In this paper BBA correction algorithm based on difference orbit multiple measurements is proposed. Numerical simulation results for European XFEL SASE1 and FLASH undulator section are presented, according to which the orbit alignment can be achieved within accuracy of about 2 microns and 5 microns respectively. The influence of quadrupole gradient errors is also discussed.
