The EMRP project ion clock addresses the development of highly precise optical clocks using laser-cooled trapped ions.  The project will evaluate systematic uncertainties and stabilities across a range of ion species. It will improve clock performance through new approaches for interrogation methods with single and multiple ions. Outputs of the project will contribute to timescale steering, to tests of fundamental physics, and to optical clock deployment in sectors such as space science and navigation.





Satellite Workshop to EFTF:


Frequency Standards with Trapped Ions


Friday 27th June 2014, 8:30 am - 4 pm.

Venue: The University of Neuchâtel, Neuchâtel, Switzerland



The workshop is organized by this EMRP project "ion clock" with participation from PTB, NPL, MIKES and CMI. Complementing the scientific program of EFTF, it will address recent developments, techniques and applications related to frequency standards with trapped ions. Invited and submitted talks in the morning will be followed by a poster session in the afternoon. A lab tour to LTF-UniNe and CSEM will be possible after the meeting. Registration is free and lunch will be provided.



Invited speaker:

S. Brewer (NIST, USA): Al+ quantum logic clock

P. Dubé (NRC, Canada): Sr+ single-ion clock at NRC

K. Matsubara (NICT, Japan): Ca+ single-ion clock: progress and plan for reducing its frequency uncertainty



We thank all participants for their contributions to a lively workshop.


We would like to acknowledge support from LTF University of Neuchâtel and the Swiss Space Office.
