Brexit or not Brexit, let our UK-based colleagues be assured that there is always a place for them in the heart of the ion trapping community !!

Dear all,

Brexit or not Brexit, let our UK-based colleagues be assured that there is always a place for them in the heart of the ion trapping community !!

Best regards,

Your editorial team


Precision measurements and traps are among the driving forces of the new Max Planck-RIKEN-PTB Center for Time, Constants and Fundamental Symmetries. More details about this new Center are described HERE. Have a look at the website for a detailed description, job offers, and recent publications!

Regarding our colleagues from the UK, COST informs us that: Brexit Update: UK government has extended the Underwrite Guarantee of Horizon 2020 to COST.  The UK government has committed to provide funding for eligible UK participation in COST Actions until the end of 2020 in case of a no-deal Brexit.
