The 2mrad interaction region and extraction line provide several machine and physics advantages, but also involves a number of technological challenges. In this paper a minimal extraction line without beam energy and polarization diagnostics is presented, which considerably simplifies the design and reduces costs. The optimization of the interaction region sextupoles, using current and proposed technologies, and an estimation of photon backscattering from spent beam particle losses are described. Overall performance is evaluated and compared with previous designs. The upgrade to 1 TeV and the possibility of including diagnostics are considered.
