Dear all,
the COST Action has an ongoing open call for Short term scientific missions (STSMs) which gives support to early career researchers for spending some time (at least one week) in a different lab in order to learn new techniques and methods and discuss mutual approaches. We would like to particularly invite female ion trappers from all associated countries and ion trappers from the central and eastern European countries to make use of this tool. Useless to say, that if you are a female ion trapper from central or eastern Europe, the world is at your feet ! Please submit your scientific projects to https://e-services.cost.eu/stsm/ or contact the STSM coordinator Lukas Klosowski.
Best regards,
Your editorial team
