      Introduction to the CLIC module layout
      The two-beam acceleration concept is currently being developed at CERN. Many different technical systems must be involved and their requirements are very stringent. For example the vacuum pressure needed for the beam physics is 10-9 mbar. Micro-precision manufacturing and assembly of RF structures are essential for the final efficiency and operation of CLIC. Since all the components are periodically repeated, it was decided to proceed with modular design. The components are assembled in 2-m long modules of few different types. After studying several configurations, the CLIC CDR baseline was defined in April 2010. The current development is focused on the Module Type 1, as it includes all the main components and systems. The current status of the design and integration will be shown in this CLIC Module introduction. Some necessary changes were done after the thermo-mechanical behaviour simulations, which will be presented afterwards.

      Mechanical and thermal modelling of the CLIC Two-Beam Module
      To fulfill the mechanical stability requirements imposed by the luminosity goals of the CLIC collider, the 2-m long two-beam modules have to be controlled at micrometer level. At the same time the CLIC modules are exposed to variable high power dissipation while the linacs are ramped up to nominal power as well as when the CLIC operation mode is varied. This will result into inevitable temperature excursions driving mechanical distortions in and between different module components. A FEM model is essential to estimate and simulate the fundamental thermo-mechanical behaviour of the CLIC module to facilitate its design and development. In the presentation, the thermal and structural modeling of the studied CLIC two-beam module configuration is presented with corresponding results.
