Description
ET requires about 120 km of underground vacuum tubes with a diameter of 1 m to achieve the design sensitivity. The baseline design foresees the production of the beam pipe in sections of 20 m, resulting in high transportation, welding, and cleaning efforts. The BeamPipes4ET project proposes an innovative production approach in which the vacuum pipes are manufactured directly on-site inside the tunnels through a continuous forming process using sheet-metal coils. To realize this concept, a fully automated robot for pipe production is being developed, and a first prototype has now been designed. This approach offers potential reductions in cost, installation effort, and environmental impact. In this contribution, the current project status, key technological developments, and a comparison between the ET baseline vacuum system design and the BeamPipes4ET approach will be presented.
