Workshop on TOPAS in association with Accelerating Biology 2019

The TOPAS User Workshop is open to all participants who are interested in learning TOPAS ( ). TOPAS (Tool for Particle Simulation) is a tool which incorporates the already-proven Geant4 ( simulation toolkit into a comprehensive architecture for the simulation of radiation therapy treatment delivery systems, imaging systems and patient dose calculations. Treatment Head Geometry, Patient Handling, Imaging and Scoring become both flexible and easy to use. Communities working in radiation physics, from High Energy Physics to Medical Physics will get benefited. The workshop covers TOPAS Installation clinic and the lecture will explain what TOPAS can do and the various paradigms behind the TOPAS design.

The participants should have basic knowledge of computers.
• Users should come with their own laptop that has one of the supported operating systems:
• Mac OS X 10.11 or newer
• Linux Debian 8 (or a Debian 8 variant such as Ubuntu)
• Linux Debian 6 (or a Debian 6 variant such as Ubuntu)
• RHEL6 (or a RHEL6 variant such as CentOS)

Note : Users who do not have one of these systems may install Virtual Box and then install Debian
8 inside that virtual machine. This is a good solution for Windows users. Users will install TOPAS on their own laptops and run some of the built-in examples.There will be discussion where users can talk about their intended TOPAS projects This could involve users giving pre-made short presentations or this could be in the form of an open discussion or some mix of the two.The group will agree on some simple thing to simulate. Then we will work together so users can see the process of building a new TOPAS simulation from the start.
