Scope and Objectives

This course is addressed to researchers in Radiation Physics and its applications. The main objective is to provide the participants with a detailed description of the new, 2019, version of PENELOPE, with an ample perspective on Monte Carlo methods for simulation of electron/photon transport. The course will consist of theoretical lectures and hands-on sessions. Basic aspects of Monte Carlo sampling methods and scoring, physical interaction models, constructive quadric geometry, and transport schemes for charged particles will be introduced in the theoretical lectures. Benchmark comparisons with experiments will also be presented to illustrate the capabilities and reliability of the code.

Hands-on sessions will be based on the generic main program PENMAIN, which operates with a variety of radiation sources (now including radioactive sources) in material structures described by the quadric geometry tool PENGEOM. The exercises will be performed with a new graphical user interface that largely simplifies the operation of the code. Hands-on sessions will deal with:

    2) the use of PENMAIN for the set of examples provided in the distribution package
    3) the design of simulations of other experimental arrangements (geometry, radiation source, simulation parameters)

As in previous editions, the duration of the course is four and a half days. To allow closer practical tuition, the number of participants is limited to a maximum of 14.
