	The beam delivery system for the linear collider focuses beams to nanometer sizes at the interaction point, collimates the beam halo to provide acceptable background in the detector and has a provision for state-of-the art beam instrumentation in order to reach the physics goals. The beam delivery system of the International Linear Collider has undergone several configuration changes recently. This paper describes the design details and status of the baseline configuration considered for the reference design.

THPMS060	Transport Optics Design and Multi-particle Tracking for the ILC Positron Source	3124
	F. Zhou Y. K. Batygin, Y. Nosochkov, J. Sheppard, M. Woodley SLAC, Menlo Park, California W. Liu ANL, Argonne, Illinois
	Funding: U. S. DOE Contract DE-AC02-76SF00515 Undulator-based positron source is adopted as the International Linear Collider baseline design. Complete optics to transport the positron beam having large angular divergence and large energy spread from a thin Ti target to the entrance of the 5 GeV damping ring injection line is developed. Start-to-end multi-particle tracking through the beamline is performed including the optical matching device, capture accelerator system, transport system, superconducting booster linac, spin rotators, and energy compressor. Positron capture efficiency of different schemes (immersed vs shielded target, and flux concentrator vs quarter wave transformation for the optics matching system) is compared. For the scheme of a shielded target and quarter wave transformation, the simulation shows that 15.1% of the positrons from the target are captured within the damping ring 6-D acceptance at the entrance of the damping ring injection line.
THPMS061	Design of a High-current Injector and Transport Optics for the ILC Electron Source	3127
	F. Zhou Y. K. Batygin, A. Brachmann, J. E. Clendenin, R. H. Miller, J. Sheppard, M. Woodley SLAC, Menlo Park, California
	Funding: U. S. DOE Contract DE-AC02-76SF00515 A train of 2-nsμbunches are generated in the DC-gun based injector in the ILC e^- source; a bunching system with extremely high bunching efficiency to compress bunch down to 20 ps FWHM is designed. Complete optics to transport the electron beam to the 5-GeV damping ring injection line is developed. Start-to-end multi-particle tracking through the beamline is performed including the bunching system, pre-acceleration, chicane, 5-GeV SC booster linac, spin rotators and energy compressor. It shows more than 95% of electrons from the DC-gun are captured within the 6-D damping ring acceptance at the entrance of damping ring injection line. The field and alignment errors, and orbit correction are analyzed.
