The Joint European Torus (JET) fusion experiment is now operated with strong involvement of physicists from many research laboratories in and outside Europe. This paper describes needs for remote participation in JET physics experiments and summarises user’s experience with the tools made available for remote collaborative work: remote computer and data access, remote meetings, shared documentation and various other communication channels. Implications for further development of remote participation infrastructure for work at JET and in an integrated European research program are discussed.
