The FCC study [4,5] is presently being formalized through memoranda
of understanding. More than 40 institutes from around the
world, in particular from Europe, Asia and North America, have
already formally joined the FCC study. In parallel, an international
collaboration board with representatives from all study participants
has been set up. At the preparatory collaboration-board
meeting on 9–10 September 2014, Leonid ‘‘Lenny” Rivkin from
PSI and EPFL (Switzerland) was unanimously elected as interim
Collaboration Board Chair. The first annual FCC workshop will be
held at Washington DC in March 2015 [42], jointly organized by
CERN and the US DOE’s Office of Science, and marks an important
milestone of the FCC study, namely the end of the ‘‘weak interaction”
phase.
