Dear
Colleagues,
In order to produce this newsletter, some work is required, which
relies to a large fraction on a paid editor putting together the
publication lists. At the end of the COSTAction we had decided to
continue this service with kind sponsors. From our first
(limited) call, we have received very rapidly many financial
contributions from different ion
trapping groups, so that the continuity of this newsletter is
guaranteed ! The
kind funders for 2015 are (in order of arrival) Stefan Willitsch,
Laurent Hilico, Stephan Schiller, and Roee Ozeri. For 2016 we already
have a list of sponsors and by the end of that period we'll hopefully
also have a new European funding. Many thanks to all who have so
spontaneously contributed, and in particular to Mirjam Bruttin and
Jonathan Home who offered administrative help!
