	CERN civil engineers are studying the feasibility of future ring colliders to complement the LHC. Infrastructure works typically represent one third of the cost of major physics projects, so it's critical that the construction costs are well understood from the conceptual stage. This poster presents the first results of the feasibility studies for two potential ring colliders at CERN: the racetrack shaped Linac-Ring LHeC and an 80km circular tunnel to house the High Energy LHC (SHE-LHC) and the TLEP. Some of the key civil engineering challenges faced in such large scale projects are presented with particular emphasis on geology, design and risk.

TUPME002	Design Integration at the International Linear Collider	lattice, positron, electron, damping	1559
	B. List, L. Hagge, J. Kreutzkamp, N.J. Walker DESY, Hamburg, Germany
	In preparation for the Technical Design Report of the International Linear Collider, a comprehensive design of the accelerator has been compiled. DESY has contributed a systematic design integration approach, which helps to achieve a complete, correct and consistent design. We use the lattice as the leading element for design integration. Geometry information including 3D visualization models are derived from the lattice, and are used to ensure that the beamlines fit and suited for access and installation. The 3D models are also used as basis for tunnel and cavern layout. As detailed designs of components become available, the lattice is adjusted and the overall models are iterated. Lists of components are derived from the lattice and are used to generate a component bill of materials, which in turn serves as basis for cost estimation and installation planning. An integrated 3D model of the entire accelerator and all the civil construction elements helps to optimize the design for example with regard to space efficiency, ease of access for installation, and life safety. Setting up design integration in an early project stage results in a better design helps to reduce costs.

WEPEA041	Actions To Mitigate The Radiation Damage to Electronics at the LHC	shielding, radiation, hadron, controls	2591

	The level of flux of hadrons with energy in the multi MeV range expected from the collisions at the LHC interaction Points 1, 5 and 8 and from the collimation system at Point 7 will induce Single Event Errors (SEEs) in the standard electronics present in many of the control equipment installed in LHC underground. Furthermore, a risk of SEEs induced by thermal neutrons cannot be excluded. Such events would perturb the LHC operation, possibly leading to a stop of the machine. Main mitigation actions will be implemented during the first LHC Long Shutdown of 2013/2014 (LS1) to reduce the SEE occurrence. This paper summarizes the mitigation measures and their associated foreseen improvements in terms of SEEs. It presents the organization process and associated planning highlighting the impacts with the overall LHC LS1 planning and the main concerns during implementation.
