      abstract     = {Observations on confinement in the first experimental
                      campaign on the optimized Stellarator Wendelstein 7-X are
                      summarized. In this phase W7-X was equipped with five
                      inboard limiters only and thus the discharge length
                      restricted to avoid local overheating. Stationary plasmas
                      are limited to low densities  <2–3 centerdot 1019
                      m−3. With the available 4.3 MW ECR Heating core T e ~
                      8 keV, T i ~ 1–2 keV are achieved routinely resulting
                      in energy confinement time τ E between 80 ms to 150 ms.
                      For these conditions the plasmas show characteristics of
                      core electron root confinement with peaked T e-profiles and
                      positive E r up to about half of the minor radius. Profiles
                      and plasma currents respond to on- and off-axis heating and
                      co- and counter ECCD respectively.},
