Dear all,

after a very successful ECTI in different locations and online, our next event is ECCTI (the Early Career Conference on Trapped Ions) initially planned for January 2022 at CERN. Due to the rapidly evolving situation in Europe, the organisers will take a decision in the upcoming days about the format and/or change of date of the conference. Please consult the website regularly!
