Room: Zoom How the course will proceed Technical aspects -- using Zoom breakout rooms to interact with lecturers during hands-on session Interacting via Mattermost for questions 'online' Exercise follow up

What is Geant4 ?

• John Apostolakis (CERN)

Room: Zoom The toolkit / library 'nature' of Geant4 and how differ from radiation transport tools ? Is there is no Geant4 'executable' ? If not, why ? Variety of existing Geant4-based application / tools. How do you use Geant4 ?

Hands-on: First look at virtual machine and one Geant4 application

• John Apostolakis (CERN)
• Gabriele Cosmo (CERN)

Room: Zoom Goals: - Familiarise with program main, contents of directories, compiling and running an executable # How to get the exercise material You can follow these instructions from the gitlab site of the exercises below "How to get the exercises" Copied below also (in case of gitlab unavailability) First create a directory for all our work (examples & exercises) : Create a new ~/g4/exercises directory, and extract it there: cd ~ mkdir g4 cd g4 mkdir exercises cd exercises Download the file below (Day1-v2.tar) to your G4 virtual machine using firefox. Note: Don't open it - just save it (in Downloads) tar xf ~/Downloads/Day1-v2.tar ls Then check it more: cd day1 ls
