Dear all,
the scientific kick-off for the new COST Action will be held 6-8 March 2019 in Granada/Spain. The idea is to create the maximum of interaction between all ion trapper groups in Europe and beyond. We strongly encourage every group to be represented at this meeting ! Please rush to register at https://indico.cern.ch/event/774881/registrations/47000/ before the deadline on 27 January 2019.
Happy New Year to all of you !

This important tool of networking will financially support collaboration visits between 5 days and 3 months. It is open to all researchers from participating countries with a priority for younger researchers. Full details about applications are given on this website and in the STSM user guide.
Please submit your project at https://e-services.cost.eu/stsm and choose COST Action CA17133 – Trapped Ions: progress in classical and quantum applications.
The nextt collection date will be 3 February 2019. If you have further question please contact the STSM chair Łukasz Kłosowski or the Action chair Markus Hennrich
