Each afternoon of the conference will feature one poster session, for a total of five days (Wednesday, Thursday, Friday, Monday and Tuesday). The poster dimensions are 95 cm wide and 150 cm high (see figure), which make them well suited for Posters in the standing A0 format (that is the portrait format). Pins for attaching the Posters will be available at the poster sessions. Please note that the Title, Authors and Affiliation should be in letters large enough to be readable at a distance of a few meters. Posters may be presented at the conference only if a corresponding Abstract has been accepted and if at least one Author has registered at the conference. Post dead-line Posters may be considered for presentation provided that poster space is available. Registered Posters will be assigned a unique code indicating the day of presentation as well as the exact board at which it should be posted (by the person presenting it). The Posters may be posted - at the earliest - at 10:00 a.m. on the day of presentation and have to be removed and taken care of by the Author at the latest at 8:45 the following morning. The J. Phys. B. publisher will award prizes to the best poster of the day. Registered participants will be able to make votes for ‘the best poster’ during each session.
