ITN Newsletter – November 2020

The COST office is taking a survey on virtual networking. If you have any bright ideas what and how we can implement interactions between Ion Trappers in the next months, you are very welcome to reply to this newsletter message. Some "technical" coffee breaks or virtual literature clubs could allow to spread information more widely. And of course you are all invited to the Precision Physics and Fundamental Symmetries seminar (see more in this November issue).
