TLEP and the future VHE-LHC will be and must be truly global projects, employing the skills, expertise and imagination of physicists and engineers from all around the world. The community at Fermilab and in the USA is especially invited to join this effort in its early stages by attending this workshop.
The goal of this workshop is to kick off the design studies for such a machine. The workshop is meant to bring accelerator experts, theorists and experimentalists, together to present and discuss all the aspects needed to prepare a design report.
