Dear all,

Due to travel and other restrictions, ECCTI (the Early Career Conference on Trapped Ions) is postponed to 26 June – 1 July 2022  in order to guarantee a face-to-face event.

We wish you a fabulous New Year 2022, which will hopefully bring us back to the ground state with a high degree of control of external perturbations. Stay positive, ion trappers !
