	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.

	Funding: EUROTeV Project Contract no.011899 RIDS An interaction region with head-on collisions is considered as an alternative to the baseline ILC configuration. Progress in the final focus optics design includes engineered large bore superconducting final doublet magnets and their 3D magnetic integration in the detector solenoids. Progress on the beam separation optics is based on technical designs of electrostatic separator and special extraction quadripoles. The spent beam extraction is realized by a staged collimation scheme relying on realistic collimators. The impact on the detector background is estimated. The possibility of technical tests of the most challenging components is investigated.

	The 2mrad interaction region and extraction line provide several machine and physics advantages, but also involves a number of technological challenges. In this paper a minimal extraction line without beam energy and polarization diagnostics is presented, which considerably simplifies the design and reduces costs. The optimization of the interaction region sextupoles, using current and proposed technologies, and an estimation of photon backscattering from spent beam particle losses are described. Overall performance is evaluated and compared with previous designs. The upgrade to 1 TeV and the possibility of including diagnostics are considered.
FRPMN092	Beam Coupling Impedance Simulations and Laboratory Measurements for the LHC FP420 Detector	4294
	F. Roncarolo, R. Appleby, R. M. Jones UMAN, Manchester
	The FP420 collaboration* aims at designing forward proton tagging detectors to be installed in the LHC sectors 420 meters downstream of the ATLAS detector and/or CMS detector. The experiment requires modification of the beam pipe material and geometry with a consequent impact on the LHC impedance budget and the circulating beam stability. This paper describes numerical simulations and laboratory measurements carried out to characterize the coupling impedance (longitudinal and transverse) and the associated loss factor of each insertion. The detectors are located in pockets of the beam tube. We study both single and multi-pocket configurations with a view to characterizing the impact on the beam dynamics. In addition, results are compared to available analytical calculations for the resistive wall impedance. * Cox, Brian et al., "FP420 : An R&D Proposal to Investigate the Feasibility of Installing Proton Tagging Detectors in the 420 m Region of the LHC", CERN-LHCC-2005-025
