Caroline Riedl was elected by the COMPASS collaboration board as next Technical Coordinator of the COMPASS experiment at CERN. Her term will start in July 2017. It will cover the no-beam period of "change-over" in fall / winter 2017/2018 during that the experiment's target region will be entirely modified to prepare for the second COMPASS Drell-Yan run in 2018 with a negatively charged pion beam: a transversely polarized ammonia target employing dynamic nuclear polarization, and a hadron absorber to stop all particles except for muons. In 2017, COMPASS is running with negatively or positively charged polarized muon beams and an unpolarized long liquid hydrogen target.
