27th Geant4 Collaboration Meeting

Description

We are glad to hold this in person Collaboration Meeting after two virtual sessions ! We are confident this will foster constructive discussions.

This meeting is hence taking place in Rennes. The meeting format is pretty standard and the agenda content will be evolved during the coming weeks. This page itself will provide news on the meeting organization.

This is a closed Geant4 meeting, reserved to Geant4 members only or to people receiving an explicit invitation by the Collaboration. 

One important aspect is VISA: members or invited speakers who need a VISA to travel to Europe/France may need an invitation letter. For this please contact the local organizing committee at clo-g4-2022~at~services.cnrs.fr (replacing the "~at~" by "@", this is to avoid too many spams...).

 

For remote participants (collaboration meeting of Technical Forum), please find the Zoom links on the following page:

      Plenary 8 - Internal Seminars & Generation Transfer Knowledge TA Beaulieu

      TA Beaulieu

      Pôle Numérique Rennes Beaulieu (PNRB)

      Geant4 has a wide set of skills and knowledge, but these are often not shared beyond the working groups. The Collaboration and its members may benefit for more knowledge sharing as this can be a seed for new ideas and developments. This could be done through a format like internal seminars, where some external could also be invited to present new trends relevant for the simulation. But this could also be used for the critical aspect of knowledge transfert from the "old" to the "new" generation. This session is to debate about such internal seminar approach, and to propose a first seminar.
