Geant4 Tutorial Course

Aug 18, 2025, 8:30 AM → Aug 22, 2025, 5:00 PM US/Eastern

Applied Research Center (ARC) Rm 125 (Jefferson Lab)

Makoto Asai (Thomas Jefferson National Accelerator Facility), Maurizio Ungaro (Jefferson Lab)

Jefferson Lab (Newport News, VA) is organizing a four day tutorial course based on Geant4 version 11.3.p02. It will cover all the application domains including high energy and nuclear physics, astrophysics and space engineering, medical applications, and newly arising industrial applications.

 

The lectures will cover all aspects of the toolkit of Geant4 version 11.3.p02 from basic installation through advanced topics including multithreading and variance reduction options, and will be interspersed with hands-on sessions that build a progressively more complex application extensible to real use. The course should be of interest both to complete novices and to those who already have some basic familiarity with Geant4. Participants are expected to have a reasonable knowledge of C++ and Linux OS in addition to basic radiation physics.

 

The tutorial starts in the morning of August 18^th, 2025 (Monday) and runs through the afternoon of August 21^st, 2025 (Thursday) with additional discussion sessions on August 22^nd, 2025 (Friday) for selected topics.

 

The capacity is limited to 50 on a first-come-first-served basis. This tutorial is in-person only and no remote participation is offered. The registration fee is $120 that should be paid as a part of the registration process. The fee covers refreshments for Monday through Thursday.

 

IMPORTANT NOTICE

Tutorial room is changed. It is now Applied Research Center (ARC) Rm 125.
