JUNO GEANT4 School

15 May 2017, 08:00 → 19 May 2017, 18:00 Asia/Shanghai

IHEP

A four days hands-on Geant4 beginner course organized by Istituto Nazionale di Fisica Nucleare will be held in Beijing (China) from May 15th to 18th, 2017.

Geant4 is a software toolkit, written in C ++, for simulating tracking of particles in the matter with the Monte Carlo approach. The software is developed and maintained by an international collaboration of scientists belonging to different institutions. Geant4 can be used for applications in high energy physics, astrophysics, medical physics, particle astrophysics and nuclear physics.

The topics of the JUNO Geant4 School will cover general aspects of high energy/nuclear physics and the specific aspects related to the JUNO physics. Lectures will cover all aspects of the toolkit from basic installation through advanced topics and will be interspersed with examples that build progressively more complex application, extensible to a real-life case.

The school is aimed at PhD students, Post-Docs and young researchers working at universities or research institutes.
