Time to say good-bye – last issue of this newsletter
Dear all,
almost 12 years that I have sent the first issue of the Ion Trapper’s Newsletter in the frame of the first COST Action on Trapped Ions. My “most read” publication has seen the announcement of numerous events, jobs, the Nobel prize awarded to one of its readers, and – even if not exhaustive – an amazing number of publications and preprints, demonstrating the incredible dynamics of an ever-growing community. From its first 250 readers, the audience has grown to over 1200 subscribers, and our follow-up shows that 50% of the recipients regularly open the email to look at the contents.
Personally, I have moved on to other responsibilities a while ago, and I do no longer have the time nor can have the necessary commitment to continue the monthly publication. I have therefore taken the decision to stop to send this newsletter.
From your very enthusiastic returns over the last years, I know that many of you consider this newsletter to be very helpful and I am proud of this. The ion trapper community should make an effort to continue a newsletter. I dare hope that there are individuals or groups who are volunteering to continue this work. This might also be an opportunity to refresh contents, format, contributions to this newsletter. I will of course be willing to help to organize the transition.
I will not end before acknowledging people who have supported this newsletter. The most important investment comes from Alejandro Bermudez who has been working on the publication lists for the last 8 years or so. He took over from Kevin Sheridan, who started to help me, when I could not juggle with your abundant scientific production any longer. There have been a couple of sponsors from the larger ion trapping groups who have financially supported this publication, and also Mirjam Bruttin who has coordinated these supports. Many thanks and a vibrant applause to all of them !
Thanks a lot for reading and see you at ECTI !
