  The European Spallation Source (ESS) is a neutron science facility comprising a linear H+ accelerator, a tungsten target station, 22 neutron instruments, a suite of laboratories and a supercomputing data processing centre. The Accelerator project represents about a third of the total ESS construction budget and several European countries participate as in-kind contributing partners to it. It is crucial to guarantee requirements consistency, clarity of interface definition and proper space allocation. Potential functional and design inconsistencies must be promptly detected and actively resolved, bridging the project from the conceptual design towards a smooth, cost and time effective installation. Moreover, while the correct synergies are established and maintained, the organisational burden has to be minimized, aspect particularly relevant given the intrinsic prototypic nature of projects of this type. This paper describes the system architecture and the tools deployed to integrate the design of the ESS Linear Accelerator and to prepare for its installation.

  The European Spallation Source (ESS) is a pan-European project. It will be built by at least 17 European countries, with Sweden and Denmark as host nations. The Superconducting Radio-Frequency (SRF) linac is composed of one section of spoke cavity cryomodules (352.21 MHz) and two sections of elliptical cavity cryomodules (704.42 MHz). These cryomodules contain niobium SRF cavities operating at 2 K. Following a redesign of its accelerator, SRF linac design shall comply with a new set of requirement, like an increase of the beam current from 50 mA to 62.5 mA and an increase of the peak electrical surface field from 40 MV/m to 45 MV/m. Requirements and the main disciplines needed to construct this portion of the linac are presented.
