Satellite meeting

Satellite Workshop on Optical Clocks Based on Multiple Ions and VUV/XUV Transitions

This satellite workshop will take place on Friday 24 April at ESA ESTEC, and will focus on recent advances in ion-based optical clocks, including multi-ion architectures and systems operating on VUV/XUV clock transitions such as highly charged ion and thorium nuclear clocks.

The program will highlight progress in precision spectroscopy, frequency metrology, and enabling technologies within the HIOC European Partnership on Metrology project. Designed to complement the main EFTF conference program, the workshop will offer dedicated presentations from consortium members and invited experts, with no overlap with EFTF technical sessions.

Participants may express interest exclusively during the conference registration process; availability is limited and subject to ESTEC site access requirements. Participants will be notified if their attendance is confirmed.
